I have encountered a minor visual issue with the RTL feature of the toolbar (I use it in the grid but I see it also occurs in the toolbar “standalone” version).
When RTL is set to true and I am grouping a set of buttons, the rightmost button of that group is not displayed properly – it has the the same looks as the leftmost button.
Update and clarification regarding the reported behavior:
The button here is a button with an Icon. With RTL and without RTL the icon is displayed as an icon. The difference between the two modes here is the layout of the toolbar items.
