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).

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.
