WordPress no longer supports many old old browsers: https://make.wordpress.org/core/2017/04/23/target-browser-coverage/
This also removes alot of no longer necessary CSS. It served us well, but we are never getting back together with IE8,9,10.
So, in the (paraphrased) words of Taylor Swift:
I remember when we dropped support the first time
Saying, "This is it, I've had enough, " 'cause like
We hadn't seen many users in a month
When you said you needed flexbox. (What?)
Then you postMessage again and say
"IE8, I miss you and I swear I'm gonna change, trust me."
Remember how that lasted for a day?
I say, "I hate the box model, " we break up, you call me, "I love css-grids."
Ooh, we called it off again last night
But ooh, this time I'm telling you, I'm telling you
We are never ever ever supporting IE 8,9,10,
We are never ever ever supporting IE 8,9,10,
You go talk to EDGE, talk to my FIREFOX, talk to CHROME
But we are never ever ever ever getting back together
Like, ever...

Currently, the "Collapse menu" item is not focusable and keyboard users can't collapse/expand the admin menu. This aims to fix it so that screen readers no longer announce it as a clickable but it remains unfocusable and thus unusable. So it's now a button.
Quoting joedolson at WordCamp Chicago 2014:
"If it's supposed to act like a button, it should be a button."
Also includes a grunt:precommit run that picked up some postcss changes to src/wp-includes/css/customize-preview.css
Fixes#29958.

This icon was added to Dashicons in 4.3, but not applied to anything in our CSS.
Uses the more appropriate `dashicons-admin-multisite` when displaying the sites menu item.

Also closes submenus when the admin menu is toggled open, as it opens below and thus can be obscured.

CSSJanus (introduced in [26107]), we had a great time with you, but sadly you don't like our fancy CSS.
RTLCSS is a framework for converting CSS from LTR to RTL, same as CSSJanus, with support for more CSS properties like `transform`, `transition` or multiple box and text shadows.
Changes:
* devDependencies: Remove `grunt-cssjanus`, add `grunt-rtlcss`.
* RTLCSS uses `/* rtl:ignore */` to ignore a rule, switch existing `/* @noflip */` to the new directive.
* RTLCSS supports the `transform` property, means we can remove some ignore rules.
* RTLCSS supports string maps for custom replace rules. This commit includes a rule `import-rtl-stylesheet` which replaces ".css" with "-rtl.css" in URLs.
Notes for core development:
* The file generation task is still `grunt rtl`.
* If you have used `grunt cssjanus` before, use `grunt rtlcss` now.
* Remember the new directive `/* rtl:ignore */`.

This removes the red channel from blues and cools the grays a bit for a more cohesive and purposeful color scheme.

Not only does this pass contrast guidelines, but it also visually appears closer to the original highlight blue used against light backgrounds.

If you want to use a Dashicon before an element you can use the class because it will not change the elements content styling. With that you don't need to copy the entire `.dashicons` styling to your :before styling anymore.
To demonstrate this change, Admin Menu now uses Dashicons classes directly.
And it fixes a glitch in IE.

The admin CSS was merged in #18314.
After a couple years as it stood,
The mess it had become just was no good.
One day we realized Grunt is pretty cool,
And said "we should use this as our build tool!"
Now we can maintain separate files with ease,
Using @import and cssmin meets all our needs.
Welcome to the future of the WordPress stylesheets,
And thanks to Slick Rick for the beats.
props jorbin for the initial patch.
