Forum Post Edit Bug - Android/Chrome

I have this weird bug that happens when I try to edit a post. Even if it's the original writing of that post.

When I click in the word box I can type like normal, however, if I ever move the cursor to change the text somewhere, another currently open Chrome tab flashes up and fills my screen as if I'm on that tab, say a Wikipedia article. Once I start typing again it goes away.

Now, you can imagine how annoying this is any time you move the cursor in the text box that you suddenly can't see wtf you're doing until you start typing, which may be the wrong spot because we all know moving your character location for editing on phones is imperfect.

This issue started a few weeks ago on my Pixel 2. I got a Pixel 4a 5G a couple weeks ago and it has continued.

Wondered if I'm alone.
