Delete partition button looks odd
The delete partition button has two squared-off corners and two rounded corners. The rightmost button in the left-side group also has the same issue, where the corners towards the middle are squared-off. This looks odd and leads the user to believe there is a hidden item present which is not there or otherwise broken.
In Pop_OS, we patched this by making the entire devtab toolbar a visually-linked widget with the devtab grid. It helps to reinforce the toolbar's UI connection to the devtab grid (and the selected partition within it) and ensure that the widget doesn't look broken, as shown:
If that works, I can put together an MR that applies that change upstream too. If not, feel free to close this issue.
Thanks in advance!
