Deleting a comment with touch breaks (almost) all interaction

[kmcnaught]

Describe the bug
If you use a touch screen to delete a comment, then you are stuck in a state where you cannot select any blocks, move any blocks, or edit any fields (using either mouse or touch).

The only way out of it that I have found so far is to edit a "show LEDs" block (which is a strange field that can be edited without explicitly selecting/opening the field). This resets something in the interaction that makes touch and mouse work again.

To Reproduce
Steps to reproduce the behavior:

1. Have a program with a few blocks, e.g. "show number" and "show icon"
2. Add a comment to block
3. Using touch delete the comment by clicking on the bin icon
4. Error: Now you cannot interact with any blocks except a "show leds"

Expected behavior
I expect mouse and touch control to continue working

I have just verified that this also occurs in MakeCode Arcade, so probably needs moving over to pxt repo?

@kmcnaught thanks for filing. Issue in this repo is fine. We will investigate.

I raised RaspberryPiFoundation/blockly#9170 in Blockly covering the odd touch interactions with comments.

my pr for this was merged so hopefully this will be in the next release: RaspberryPiFoundation/blockly#9172
