Timelines begin to freeze, glitch, and throw false disconnection errors (the issue is definitely with the timeline and not my internet connection, as it only happens in timeline view, and doesn't affect any other website or online service I'm using at the same time) if I try to add a new historic event once that timeline exceeds a certain number of events. The most common glitch is that trying to add a new event results in it just loading indefinitely and never actually creating it, but crashing the entire timeline, or creating the event but not attaching it to the timeline, are all common, as well as the false disconnection errors.

I recently created a new timeline and counted the number of events at which this started occurring (72), but I don't know if that's a consistent limit, or if the number of connections or some other factor makes an impact.

This is consistent across timelines and across multiple worlds.

For some reason I cannot fathom, switching a timeline into list view makes this issue begin to occur at a lower number of events than if I keep it/switch it to default view, although it is still present in list view.

It's also probably relevant to note that I tend to heavily use timelines and historic events in many of my worlds; most have 10+ timelines, and my largest world has 70, and those timelines tend to contain high numbers of events - the 72 event timeline mentioned above is a pretty short one for me. I also tend to fill out at least some of the connection fields for most events, and most events appear on multiple timelines.

Create a timeline with a high number of events while in list view. (Possible also create a lot of other timelines, if that seems relevant).
