The test has already been added to both PRs.

Hm, that can indeed happen. On the other hand, if the dirty flag is reset even in the case of an exception, parts of the UI may not be updated for a long time until a node in that area receives a change. The question is which of these two options is the least harmful.

I'm fine with each of them. What do the others think?
