I set up a "Sort by" button in the Dolphin Toolbar with an self-configured icon because this button does not have an icon by default.
So it looked like this:
After a restart of dolphin the icon was missing and it looked like this:
I tried the same thing with other toolbars at other applications but it only happened at dolphin with the "Sort by" button.
Steps to Reproduce:
1.Set up a "Sort by" button at the dolphin toolbar with an icon
The self-configures icon was gone
There should be an icon
This bug only occurred at the "Sort by" button for me. I tried it with other buttons and it worked fine.
