Review process

This 2-passes review process aims to:

• develop skills of junior reviewers
• limit the workload for senior reviewers
• limit the number of unnecessary changes by the author

1. The author creates a PR.
2. Review process:
   1. The author assigns the junior reviewer.
   2. The junior reviewer conducts their review:
      • Resolves their comments if they are addressed.
      • Adds comments if necessary or approves the PR.
   3. The junior reviewer assigns the senior reviewer.
   4. The senior reviewer conducts their review:
      • If there are no unresolved comments on the PR → merge.
      • Otherwise, we continue with 3.
3. The author responds to comments and/or makes corrections, and we go back to 2.

Notes:

1. The author can request a review at any time, even if the PR is still a Draft.
2. In theory, there should not be more than one reviewer at a time.
3. The author should not make any changes:
   • When a reviewer is assigned.
   • Between the junior and senior reviews.

What is the point of assigning undefined as the default value?
Is it to prevent vue from converting undefined to false?
If so, is there any point in having undefined instead of false here?
Or maybe this is something I missed in the guideline?
In that case, why selected is not handled?

[MathieuRA]

In the DS, i can see a counter prop.

Based on the Tabs bar changelog, the v2 implement the scroll bar option

selected: isSelected(name) maybe? In order to sync name. (or isCurrent() if the proposition is accepted)
