Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

Expected result
