Mai Grid Issues when in reusable block - Post Choices Do Not Save or Come Up and Drop Down Gets Stuck

[BrandiCap]

Basically when using a reusable block that has grid in it, when you try to switch to a different post it sometimes doesn’t work. (I have seen this using a block pattern too, so not convinced it's limited to reusable blocks and more of a grid issue.) Here’s a video showing this: https://share.getcloudapp.com/Z4u1v9rJ. I have seen this on BizBudding, but also client sites. Sometimes the drop down of post choices even gets stuck and doesn’t go away, even after you have picked one too, which is super annoying, and I have noticed times when I am adding a grid item by choice and put in the exact post title, it doesn't come up as the first option (or anywhere near the top for that matter). These all may be separate issues, but wanted to note them all because they've been around for a while, and I keep forgetting to actually log the issue.

Here's another video and screenshot. Video shows me changing the post entry (and it seems to take the change), but if you refer to the screenshot you can see it didn't go through upon updating the page. (I didn't convert the reusable block to regular blocks, here, though I don't think that should have made a difference.) You can also see here how the drop down gets stuck and floats as I scroll.

I'm not seeing this in the latest develop/beta. I'm thinking this is the ACF bug that's fixed in the new updates.
