Romain, Could you please evaluate the priority here?

Flags: needinfo?(rtestard)
Flags: needinfo?(rtestard)
Priority: -- → P2
Whiteboard: [proton-tabs-bar][priority:2a]

I cannot reproduce this anymore, Hani, can you please confirm if you're still seeing it?

Flags: needinfo?(hani.yacoub)

I managed to reproduce this issue only on Windows 7 x64 but with a different scenario.

  1. Have a couple of pinned tabs without any tab opened.
  2. Minimize the window.
  3. Open a new tab.

Screen recorder:

Flags: needinfo?(hani.yacoub) → needinfo?(rtestard)
Whiteboard: [proton-tabs-bar][priority:2a] → [proton-tabs-bar] [priority:2b]

Thanks, now adjusting priority to P3 given complexity to reproduce and low impact when encountered.
