Keep "Tab list" panel open when a connection is closed from the panel

Hello,
I have noticed a strange behavior, which doesn't seem normal, and is not user friendly.

In the following panel, which I have set to auto-hide, whenever I click on one of the "Close" icon on the right, the whole panel disappears, which makes it more difficult to close another tab right away.
I then need to move the mouse again to "Tab list" on the left to get the panel back and then I can close another one.

In my experience, having used side panels in other apps, it shouldn't disappear unless the mouse either move away from the panel, or if a click happens outside the panel.
But clicking anywhere in the panel, shouldn't make it disappear.

Is it something you can fix/enhance ?

This would be great and more consistent.

Thank you
