Regression: Panel tabs use wrong capitalization

[alex-kinokon]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.129.1
• OS Version: macOS 26.5.2

Steps to Reproduce:

1. Enable experimental UI.
2. Observe the panel tab.

where the tab title is improperly capitalized. In French, only the first word should be capitalized. Note that the locale text itself was already properly capitalized as “Console de déboggage”, so this CSS declaration does not even need to exist.
