Key signature changes are not updated on next pages.

Engraving bug

Bug description

For example, a score that starts in D Major will switch to C Major in the next measures/pages. If I select C Major, A Minor button from the palette and put it in the second measure of the second page, 2 sharps still appear on the next pages. This issue only happens on C Major, A Minor button.
As I understand it, this only happens with multi-instrument scores, and it happens after page two.
I made a video so it can be better understood from it.

Steps to reproduce

1. New Score / Create From Template / Orchestral / Clasiccal Orchestra / Next
2. Key Signature / D Major / Done
3. Palettes / Key Signature / C Major, A Minor place in the second measure of the second page
4. still looks sharp in front of the next page/pages

I can confirm this. And also something is wrong with undo behaviour

This appears to also be fixed by #18500.
In the 4.1 RC the problem exists as described, though it seems that it corrects itself as soon as a note is added after the C major key signature change.

@oktophonie I dont think, this "next page ks" issue is related #18500

I tried latest master (without #18500), and it works also there.

But strenge ks after undo seems to be fixed by #18500.
I say this, just to know, that adding only #18500 into 4.1 potencialy wouldnt fix major issue "next page".

That's covered in this huge bug #17718

I can confirm. The "next page ks" issue is fixed in latest nightly master (4.2) and still occurs in latest 4.1 nightly build

But strange ks after undo seems to be fixed by #18500.

Nope, unfortunately still happens in #18500 builds too

Would love to find what's fixed this in master and cherry-pick for 4.1.1 then!

fixed in #18697
