Fixes #91135.
Fix regression caused by Save current tab in
TabBar
andTabContainer
#83893, where setting the current tab right after entering the tree would make the value be reset to 0.The other one is bit more complicated (caused by Allow no tabs to be selected in TabBar and TabContainer #87194). It happens because the tab visibility change is also triggered if it becomes visible in the tree (even if it was already set to
visible
),and I'm not sure how to fix this without some ugly hackiness.Alright, did the cleanest attempt I could, suggestions are welcomed.Thanks to @jsjtxietian for pointing me in the right direction and saving me time.
