Writer field content deleted, when renaming page slug

[FynnZW]

Description

When a page slug is renamed, the last writer field on the page gets it's content deleted.
Saving then will lead to content loss (very possible if that field is out of view).

Possibly related to these issues: #6351 and #5659

We also have a similar issue with the Markdown field: fabianmichael/kirby-markdown-field#164

Interesting, really seems to only happen on very fast connections, must be some kind of race condition. I'm also seeing my bug locally using Valet as a dev server (I'll add that in the bug description), doesn't seem to happen on a real production server so far.
Edit: Just updated my Valet installation from 4.6.1 to 4.7.1, bug still present

I can reproduce this. For me it seems to happen so far always to the last writer field on the screen. Is this something you can confirm from your experience too @FynnZW?

Yes, it seems to be always the last writer field.

Reminder: this is still a current issue (Kirby 4.4.1) and occurs also in Kirby 3 installations...

+1 here.
Throttling my connection to Slow 4G fixes it so it's really looking like race condition.

I'm glad to say that we seem to have a solution. #6972 We need a bit more testing though.
