Hmm, I really don't like IsXXX methods with side effects. I'd prefer to not have this commit at all to be honest. Instead, we should maybe just do this on v0.14.0.x:

Note: the way txes are synced via signals has changed a lot since 0.14, so
I propose to backportit will need its own fix.06e20a8 to fix the same issue there while avoiding merge conflicts in the future
