Code folding is buggy. Have some functions that have inner functions or other foldable stuff like classes with methods and inside the method maybe some inner function? It will only show folding buttons sporadically, seemingly without pattern.
Also standard text editing stuff like "double click and drag" no longer properly works without issues/has weird effects and behavior. The inspection of identifiers interferes with being able to properly select text.
The issue search is stupid too, often doesn't find the things one searches for.
You must be logged in to search properly too.
Most of the functionality is tied to running that JavaScript.
In short, it shows typical signs of a platform that is more and more JavaScriptianized with bloated frameworks making things work half-assed and not properly tested for sane standard behavior.
But there is more. Their silly AI bots closing issues. "State bot". "Dependabot". All trash or half thought out annoying (mis-)features. Then recently I read here on HN, that apparently a project maintainer can edit another person's post! This reeks of typical Microsoft issues with permissions to do things and not properly thinking such a thing through. Someone internally must be pushing for all this crap.
