Red asterisk for required items not disappearing when required items initially populated by triggered calculations

[pbowen-oc]

teps:

1. Open the attached form as a new record (/single/fs/c/i/) -
2. Calculation not firing on new form.xml.txt
3. Click Yes for "Was Temperature Measured?" item
4. Observe that temperature entry fields appear with initial values of 98.6 and ⁰F.

Expected:
The temperature entry fields have values, so they should no longer have the red asterisk that indicates an empty required item.

Actual:
The temperature entry fields still have red asterisks despite having values now.

(ignore circled area, this ticket is about the red asterisks above it)

Note that changing the values on the form afterward, changing the trigger item to make these items non-relevant then relevant again, or reopening the form (whether there were changes or not) causes the red asterisks to disappear as expected.

Sample instance to use when reopening the form -
Calculation not firing on new form.instance.txt

Reopening form working as expected:

This was present in 6.0.0.oc-7 (and possibly earlier).
