New highlights working in unfocused editor

[dimateos]

Right now, when you have the same file (or simple equal filename?), new highlights get matched and colored only in the first editor (by creation order)... instead of the currently focused one:

This is more noticeable now with detachable editor windows, but happens with split editor groups too.

A common use case of having the same file opened twice is reading some part of a large file while editing other.

Request

• IMO coloring of new highlights should happen in the focused editor, basically where edits are happening.
  • Coloring of non focused editor seems more of an edge case (looking at the exact same text in two editors), plus could potentially affect performace?
  • But ideally, at least, coloring could be recalculated for an editor when it re-gains focus. Right now you have to switch to a different tab (hiding its content) and back.

Regards! Thanks for the extension :)
