editor.occurrencesHighlight: "multiFile" not working

[GioGiglio]

Type: Bug

1. set editor.occurrencesHighlight to "multiFile"
2. open two files side by side
3. select a word (that is present in both files) in one of the files

the editor will highlight all occurrences of the same word in the current editor, but not on the other one, and viceversa.

Something else I've noticed: if I restart vscode and immediately select something on one editor, the highlight will work on the other editors as well, but if I wait a couple of seconds after restarting it doesn't work anymore. This also happens with all extensions disabled and without settings customizations except for editor.occurrencesHighlight.

Apologies for the late reply, is the issue still occurring in the latest stable release (1.91)? Also, are you expecting to see all textual occurrences (just the same string, no semantic knowledge) highlighted, or are these semantic occurrences (ie an exported class in another file, etc).

If the issue is reproducible, I would appreciate consistent/detailed steps, as I am unable to reproduce this bug on my current environment. Thanks!
