However, now if I change anything in both windows, the "cursor" jumps to where it was changed and no longer respects the "folding" in the previous window, as shown in the images below. 1 - somefunction2 window 2 - If I change something, window 1 "lose folding" previous ! 2 - somefunction1 window 2 - If I change something, window 1 "lose folding" previous ! Is there any configuration to keep the feature prior to this update? Thanks.
Yes, I can reproduce. This was an intentionally change, but we didn't think of the split screen scenario The idea is that if we detect that a folded range has gotten larger (or smaller), we expand it. FYI
Hey Thanks for the answer, do you think we will have any option to disable this change? I believe the old format helps a lot when there are multiple codes in a single file and split screen is needed.
I don't think the line you identified is the culprit here. I think this is happening because of the following code in I don't know why the test for a change in the size of the range is there. I think that just testing for would be correct.

But I'm not 100% sure. Can you think of a reason for the decorated range to change which would require that we unfold? I've done a test with decRange.endLineNumber - decRange.startLineNumber !== foldRange.endLineNumber - foldRange.startLineNumber removed from that line and the split view then behaves properly, not auto-expanding things. It would be a different matter if the range returned by the folding provider changes, i.e. the test you identified. I think unfolding is correct in that situation.
Hey guys, any news? I updated to version 1.72.2 and the problem still persists, in fact this is very annoying
Nudge
are there any plans for fixing this issue? As a Vue dev, I must admit that this auto-expanding behaviour is super annoying when working with single-file-components.
I'll look at it in November.
Hi , any plans on fixing this? It is past November.
, I have updated VSCode to 1.75.1 and this is still a problem - the issue I described in is still the same. So it doesn't seem fixed.
The fix will be in 1.76
