All the actions are in a block without a condition, so they are being executed continually. If you put them inside a on start of layout trigger so they only happens once, everything works as expected.

Will look into it further, even though it's a strange use case, it should work.

Ouch yes I see, I stumbled on this as I am trying to make another Bugreport, I wasn't looking carefully. Sorry to bother you with something that doesn't make sense, feel free to just close this Bug.

It is possible to fix this, but it's tricky and since it's a rather unusual use case, I'll leave it for sometime later in the future.
