Browserslistc and Android

As I discovered in #30986, if I remove Android from .browserslistrc tests fail on Legacy Edge. For example: https://github.com/twbs/bootstrap/runs/788301337?check_suite_focus=true

This might be an issue with Babel, opening an issue to track it.

@alpadev thanks for testing it out 😃 That being said, I think the issue is that this should have been handled by Babel, shouldn’t it?

Also, check out my comment above; I’m not sure if there’s a convention about the dist files syntax. Traditionally, we were using ES5 or even ES3. Now, on main we do use some modern APIs already.

EDIT:

Here’s a temp branch to see the size diff:

• https://github.com/twbs/bootstrap/compare/main-xmr-browserslist
• https://ja2r7.app.goo.gl/nJogapDpNshsgcUV6

The difference is quite big… Putting aside that it’s probably a breaking change to land it now, though.

Alright, after discussing this with @mdo, we agreed to proceed with dropping Safari < 12, thus we should be able to get dist files with modern code. I’ll prepare a PR tomorrow.
