guttenber behavior since 5.5

Hello,

Has anyone noticed inconsistent behavior in the Gutenberg editor since version 5.5

For example, I periodically lose focus while editing a text block (paragraph). The block becomes unavailable for editing and I have to make an additional mouse click on another block, then back on the current one to continue editing.

Another example: sometimes the “Add block” pop-up button (with a plus sign) does not appear between individual blocks and it is impossible to insert a new block at this place. You have to insert a new block above (or below) and then move it to the right place.

These oddities started with version 5.5. The previous version seemed much more convenient to me.

I work in Firefox, latest.

Thanks.
