Description:
Starting with version 7.6.x the structured animation control list of Impress is corrupted.

What I mean by that, is that in all pre-7.6.x versions, when designing a slide with multiple interrelated animations, the sub-panel for adding animations displays a *structured* list of the animation process, also annotated by each animation's type.

However, in versions 7.6.x the animation sub-panel displays just a list of text without any structure and/or annotations.

This behavior happens both, on linux and win11, is independent of the icon set, is independent of the user account, and also happens for a fresh install of libreoffice.

This behavior renders creation of animations with even just a very low degree of complexity almost impossible.

Steps to Reproduce:
1. Open new 1-slide presentation
2. Insert a couple of text boxes
3. Animate them by making them (or groups of them) enter / exit the slide
4. Look at the list of animations introduced in the animation panel

Actual Results:
For the preceding step 4. one observes only a new-line-separated list of text referring to the animated objects without any structure and information.

Expected Results:
For the preceding step 4. one expects to see a structured list (including indentations) which shows the animation-step sequence, involving key-clicks, symbols for "entering" or "exiting", type of animation, groupings of animated objects, a.s.o.
