Keyboard automatically resigns and becomes active in an infinite loop

Steps to reproduce the behavior:

Can't provide these. I've been simply adding one block type after another to monitor the memory usage. At some point, I saw two "Start typing..." blocks at the bottom and the keyboard started doing it.

Expected behavior
n/a

I managed to stop it be pressing (+) a few times.

I was able to reproduce it again without doing anything special. I was just adding more blocks.

Here are some more videos to demonstrate what's happening. I'm not performing any interactions. I managed to close it
and save the draft, but only after some struggle because the confirmation alert also kept jumping up and down.

Thanks @kean for reporting this!

It would be worth us testing on or after 1614edc where we merged the React Native upgrade to see if anything acts differently. 🤔

Hey @kean 👋 we are currently working on a fix for this, would you mind testing this build when you have a chance to see if it fixes it for you? Any feedback would be appreciated, thank you!

Hey @geriux, thanks for addressing it so quickly. I tested it, and after adding hundreds of blocks, it's still going strong with no issues. It feels snappier too; maybe it's just me.

Unrelated:

• It would be nice to entirely eliminate the keyboard jumps when adding new paragraphs
• "Start writing..." placeholders looks like regular text; it would be nice to make them gray

Thank you for testing! Happy to see that it fixed the issue for you! And that it feels snappier 🎉

Those are great suggestions!

Hopefully, we'll be able to avoid hiding/showing the Keyboard in the future when we improve the current implementation we have with Aztec.

As for the placeholder, I'll create an issue to track it. Thanks again!
