Timeline: some items are hidden in some usecases

[christophs78]

Describe the bug

In some usecases timeline-items are not show until zooming out.

Look at the screen-recording:
https://github.com/primefaces/primefaces/assets/10461942/14c2bb17-ec86-4291-94f3-6fa09adf1aa4

Checking one of both checkboxes still works. After checking both Max 1 and Max 2 are missing until you scroll out.
From my feeling this may be a bug within https://visjs.github.io/vis-timeline/docs/timeline/.

There are a bunch of open PR's https://github.com/visjs/vis-timeline/pulls

The developer apologizes but he said he basically has no time for VisTimeline so not sure when any of those patches will be applied. Might be worth applying some of them to see if it fixes your issues.

I looked through the vis-timeline pulls. Nothing seem´s to fit to this issue.
There´s a small chance to find some point in the future where i´m realy motiviated to dig into there code-base. Otherwise (most probably) this will be a "won´t fix".
