Can't remove breakpoint in Disassembler

1. Open a project.
2. Set a breakpoint in main function.
3. Start the debugger and let it stop at the breakpoint.
4. Click on the "Operate by Instruction" icon to open the Disassembler.
5. Try to remove the breakpoint in the Disassembler.
   It's not possible. Clicking it adds another breakpoint in the same location. The context menu does not offer an option to remove the initial breakpoint.

Clicking the breakpoint should remove it just like in the C++-editor.
