The application has #informUser:during:

Maybe we should add an #informUserDuring: also letting the developper manage the label himself instead of providing a default label?

So first step is to add informUserDuring: in Spec then use it here

[jecisc]

Hum... In fact we can directly use #informUser:during: I think. I'll propose a code update to fix the problem

[jecisc]

I proposed a fix that should work I hope

Suggested change

	self halt. "We should not use UIManager default.
	Now the replacement is not clear to me. SD."
	UIManager default informUserDuring: [ :bar |
	bar label: 'Fetching incoming commits'.
	bar max: remotes size.
	self application informUser: 'Fetching incoming commits' during: [ :bar |
	bar max: remotes size.

I also did a PR to fix some of the CI's failures: #1990

Tx cyril. I found the fix for the unclosing tabs :) My mistake.
