Hiding fields depending on category does not work

Reproduce ticket creation in the simplified interface using a block with fields and a hiding condition based on ticket category, then inspect the plugin code handling conditional block visibility and form layout updates. Compare the category condition with the working title condition; done means the block hides when the specified category is selected without layout or CSS breakage.

Bug description

When I setup a block to be hidden depending on ticket category, block is not hidden in simplified interface. Haven't tried in standard interface since it does not meet our requirements.

Block configuration:

Block fields:

Block hiding condition:

When a user begins to create a ticket, block is shown (which is expected to happen)

But when the user sets the category by which the block has to be hidden, some erratic movement happens and the field is still shown with broken CSS, a.k.a. moved rightwards and wider.

I've tried setting the condition to the ticket's title and this works correctly, block is successfully hidden and works like a charm.
