Block options title shows "undefined" instead of block type

[lmischner]

Describe the bug
When I open the 3 dot menu for a block, the type of block no longer shows in the menu's title (where it used to say " block options" it now says "undefined block options"). If I opt to transform the block, it similarly shows "transform undefined to" instead of "transform paragraph to".

To Reproduce
Steps to reproduce the behavior:

1. Access JP or WP in either iOS or Android
2. In a post, tap the 3 dot menu on a block
3. Note menu title does not indicate what type of block it is
4. (You can also tap "Transform block" and see the menu title behavior there as well)

Expected behavior
I'm not sure when exactly it broke, but it shows the correct behavior in 21.2:
