timeline crashes with time intervals under certain conditions

[offtherailz]

Description

Given you set the time line to range mode and you have a guide layer with a few data, when you try to expand the timeline, it crashes.
This because the function that calculates the time range data do not take in consideration the case when getDomainValues returns a intervals ( e.g. 2021-01-01T00:00:00.000Z/2021-12-31T11:27:21.389Z )

How to reproduce

• Import the attached map or open the linked map (created by adding a layer with time intervals and setting timeline to range )
• expand the timeline
