[BUG?] Tab Strip tabData Custom Column Deleted When Adding Tab with Customizer

I have added a custom column to the tabData dataset property on this tab strip component. When I use the customizer to add a new tab to the tab strip it deletes the custom column. So, I must resort to adding the tab manually using the dataset editor instead of the customizer. This may be the expected behavior, but it may be beneficial to update this behavior not to touch “unused” columns if possible. This would be very much appreciated.

It only does this when adding an entirely new tab. If I add the tab using the dataset editor and then change properties in the customizer it doesn’t touch the custom column

Common behavior on tables, too. From what I've peeked at, not a simple ask.
