Executed Tests

Manual tests, see above. This is a style change only, and it doesn't change the UI layout, so it should be pretty safe for automated tests.

Expected merging strategy

• Prefers squash: Yes
• Backport on branches:
  • 15.10.X
  • 16.4.X

Technically, this looks good. However, looking at this pull request and the issue again I wonder if there is an agreement that these colors should actually be applied to the links. I think it would be good to have small proposal to agree about this. The issue also mentions introducing new color variables for the links as an alternative from what I understand.

Setting it as a draft:

If option 1. is picked (the one currently implemented), make sure to correct the looks of this solution with the default Iceberg,

Option 2 was picked. I updated the PR to implement the second option with a new Flamingo ColorTheme variable. After a self review, I'll post the updated status and reopen this PR for review :)

In the current state of the PR, here is what changing the value of the colorTheme variable to pink amounts to:

When hovered, the links take the same color as the other elements (same behavior as before applying the changes from this PR). We did not introduce a @breadcrumb-link-active-color so we're still using @breadcrumb-active-color.

Here's what the UI to update this value looks like in Iceberg:

---

By default, this variable takes the same value as @link-color, which results in the same UI as what was obtained before. This value is overriden if the user explicitely sets the value in the active colorTheme (or sets it in a SSX).
