Suggested merge commit message (convention)

Fix: Table selection handler should not be truncated inside a block quote. Closes: ckeditor/ckeditor5#3322

---

Additional information

Because of no Edge support we can't use such CSS syntax:

.ck-content blockquote .table:first-child {
  margin-top: calc( 1em + var(--ck-widget-handler-icon-size) );
}

Q: Why is

.ck-content blockquote {
    overflow: hidden;
}

in the first place?

It's because ckeditor/ckeditor5-image#140 (comment).

I was wondering... this whole thing is totally related to the UI, not to the content. For instance, when the editor is destroyed and .ck-content styles are still in use (inline editors), this would look weird.

Another thing is, it only takes a single change to --ck-widget-handler-icon-size, and the content styles blow up and we have a regression.

So, what about using UI styles instead of content styles with --ck-widget-handler-icon-size in calc()?

BTW, there's also this case
