Selector suggestion in Style editor tab

[5e-Cleric]

Your idea:

Other editors have an automatic suggestion box with the most used selectors, and it would be a great addition to our tool.

I got the idea from the MagicCSS extension:

And asked in their github for how they come up with this list:

webextensions/live-css-editor#141

This should give us an idea on where to start. We'd need to have the DOM rendered to grab a list of al used classes, then hopefully remove the ones we don't want users to use(.columnWrapper, .blank...) and provide those as suggestions when writing a dot, or any selector.

Does codemirror support suggestions?

We use suggestions already for emojis.

Also, jeddai already basically made this in PR #2905, but for the text editor tab
