on microsoft edge latest ^^ and the same issue om chrome beta

the issue doesn't exist when using desktop versions even the ones bundled to andriod like kiwi browser

This is weird.

y-prosemirror renders the username using ProseMirror's Decoration.widget. I create a DOM element and feed it into the widget. I'm not doing anything edgy here..

There seems to be a recent change in WebKit that affects ProseMirror's ability to read changes. @marijnh do you have an idea what's going on?

someone said its an andriod issue so this is kiwi browser (they take chromium for desktop and bundle it somehow for andriod so you can use chrome extensions etc)

i feel like the issue is the browser thinks the username is part of the text document so it trys to delete the space or the first char of the name
