:emilio, since you are the author of the regressor, bug 1799901, could you take a look? Also, could you set the severity field?

That's the behavior on other platforms (just checked on Windows), so even though technically a regression on GTK, it isn't a GTK bug.

This code is executed on ViewShown, probably should be executed on ViewShowing or something?
