Block Editor freezes on iPad

Continuing the discussion from Using App Inventor on iPad for Development:

@ewpatton Blockly did not come up with a solution yet (and they could only reproduce it for iOS 12), but I did some testing in the meanwhile in App Inventor and Blockly:

I’m still able to reproduce the freezing GUI in App Inventor (nb183c) with an iPad on iOS 13.4.

But I was never able to produce a freezing GUI on “Try Blocky” at

So it seems to me, that there is some problem with the implementation of Blockly in App Inventor?
