Multiple result tabs in Material Dark are indistinguishable

[renderse7en]

Originally reported this in HeidiSQL (HeidiSQL/HeidiSQL#956) but he said to report it here instead, and added an "upstream" label there, so I'm assuming it's more to do with the theme itself rather than anything he's doing in Heidi specifically. I'm copy/pasting my original issue here, hopefully this is enough for you to go on.

Steps to reproduce this issue

1. In a single blank Query tab, write multiple SELECT queries (e.g., "select top 100 * from table1; select top 100 * from table2; select top 100 * from table3, ...")
2. Execute them.

Current behavior

It makes individual tabs for each query below the SQL editor textbox, e.g., [table1 (1r x 21c)] [table2 (2r x 9c)] [table3 (10r x 49c)]
but there is no visual way to distinguish which tab is active. The tabs above the editor box have a light blue strip at the bottom to show which tab is active, but the result tabs below the editor do not.

Expected behavior

The result tabs below the SQL editor textbox should get the same "active" styling as the tabs above it; that is, a light blue strip at the bottom of the tab.

Environment

• HeidiSQL version:
  11.0.0.5919 (though the issue was also present going back to 10.0)
• Database system and version:
  SQL Server 2017
• Operating system:
  Windows 10 x64

Hi @renderse7en ,
Thanks for reporting.
Unfortunately I don't have enough time to dig into this issue for now, but I'll add the help wanted label... If someone want to send a PR, you're welcome.
