Presentation: Animation "jumps" some steps during a slideshow

[estux]

Describe the Bug

I have a 5 points numbered list text inside a slide and every line (or point of the list....e.g. " 1. some stuff ") has its own "Venetian blinds" animation associated. I didn't change the standard setup about timing and other stuff.
When I start the slideshow mode in Libreoffice desktop it behaves as it should, showing one line at a time when I press the keyboard button, but if I start the online slideshow with the same file, at the point 4 it stutters and shows together point 4 and 5 and jumps to the next slide, and as I have 3 more points in the new slide it behaves the same, quite missing the last 2 points again.

Steps to Reproduce

1. Have a 5 points numbered list text inside a slide in a presentation file (+ optionally another slide with 3 points more)
2. Associate a "Venetian blinds" animation effect to every point in the list (sequentially) (do the same also for the points in the second slide, if you have it)
3. Start slideshow mode
4. The first three points appear sequentially after pressing (every time) a button in the keyboard
5. the forth point doesn't appear after pressing the keyboard button (and it doesn't appear even if you wait)
6. press again the keyboard button to see point 4 and 5 appearing together and then going straight to the next slide
7. the same happens with the points in the new slide, the last 2 ones don't appear at all and pressing the button makes you jump to another slide.

Expected Behavior

I expect the animations to follow sequentially what I setup before.

Actual Behavior

At some point it seems like the rendering is stuttering and you miss some points of the presentation or you can see fast jumps to the next slide. Basically the animations are not working well and precisely.
