ToolBar with AutoOverflow not working on Mobile

Hi.

I have my ToolBars set with AutoOverflow = true.
It works fine when the parents resize, which shows the drop-down button accordingly.
But testing on a Mobile Phone, it just truncates the ToolBar at first. Then, if I Rotate the phone to Landscape, it shows the whole ToolBar, and then when back to Portrait, it does work fine showing the drop-down button for the Items which don’t fit anymore.
I have attached pictures of before and after Rotating.

Any workaround I could apply to this one?

Thanks in advance.
