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...

The Text widget in legacy mode omits TinyMCE and retains old behavior for matching pre-existing Text widgets. Usage pointers added to default visual mode appear when attempting to paste HTML code into the Visual tab and when clicking on the Text tab, informing users of the new Custom HTML widget.

The last time a new widget was introduced, Vuvuzelas were a thing, Angry Birds started taking over phones, and WordPress stopped shipping with Kubrick. Seven years and 17 releases without new widgets have been enough, time to spice up your sidebar!

Links used as UI controls that behave like buttons, should be buttons.
- changes the widgets "toggle", "Delete", and "Close" links to buttons
- uses `aria-expanded` to announce the state of the toggle buttons
- increases a bit the clickable area of the toggle
- ensures the "circular focus" doesn't get cut-off in some browsers by centering the toggle arrows
- uses a `<span>` element with an `aria-hidden` attribute to hide CSS generated font icons from assistive technologies
- standardizes on `.toggle-indicator:before` rather than `:after`
- changes two `#f00` reds in `#dc3232`, see #35622Fixes#31476.
