Description

User reports via Zendesk 5472:

When I embedded that timeline using an iframe, and modified the 'initial zoom' to 10, I noticed the timeline slowed down and nearly crashed when loading. When I dialed it back to 7, it started loading as normal.

I haven't experienced any performance issues modifying the initial zoom on other timelines I've created, so I suspect it has something to do with the using the very specific 'Time' values and zooming in.
