Nested exhibits appear outside of parent timeline

[saekow]

Steps to reproduce:

1. Create a timeline with a length of 300 years
2. Create a nested timeline with length of 3 years.
3. Create two exhibits inside the nested timeline
4. Exhibit 1 can have any valid date within the nested timeline
5. Set Exhibit 2 with date equal to end date of nested timeline

Observed:
The two exhibits will appear outside of the nested timeline, even after refreshing.

Notes:
If the nested timeline is increased in length by a few years, then the two exhibits will correctly appear inside. Could minimum exhibit size or method of calculating exhibit size relative to parent timeline be adjusted?
