Change 220993 had a related patch set uploaded (by Amire80):
Link categories to the respective category pages

Screenshot based on the patch:

Links open in same tab.

This change makes it hard to add categories to the target article that were removed before.
When a category in the translation is removed (by clicking on the "X"), it can be added again by clicking on the category from the source article. With the change, that action also makes the category to open.

Exploring categories is an interesting aspect to support, but it may need to think a bit more on the design of it to avoid conflicting with the category adaptation process.

Not urgent, just a pet project :)

I added link icons in both columns. Maybe it's better to link the text and add an icon that re-adds a removed category. Whatever Pau says.

For exploring content, I'd like to keep the behaviour consistent with the rest of links in the translation: keep the elements selected and showing a pair of cards in the tools column representing the source and target categories. I can add more design details (feel free to add the ticket to any upcoming sprint).
