Too little contrast in progress indicator of inactive tab in light theme

No response

Steps to reproduce

Configure the terminal to use the light theme (not legacy), and a tab bar separate from the title bar. Open a PowerShell tab and run a command to output the OSC that sets 50% progress: "`e]9;4;1;50`e\" Do the same in another tab.

Expected Behavior

The progress indicators in the tab bar should have good contrast so that I can see how much progress has been made.

Actual Behavior

The progress indicator of the inactive tab is too light and doesn't have enough contrast to the light background:

Compare to the dark theme, where both progress indicators have adequate contrast:
