Time tracking user interface setting doesn't show decimal values after refresh

Summary

Based on Configurating Time Tracking documentation, decimal value should be accepted for:-

• Working hours per day
• Working days per week

But, now both of the setting is not accepting decimal value

Steps to Reproduce

1. Go to Time Tracking configuration page
2. Change Working hours per day value to 8.5
3. Then, go to other page and come back to Time Tracking configuration page.

Expected Results

The value is saved and displays as 8.5.

Actual Results

The value is saved in the back-end, but the user interface does not show the decimal value (adding to confusion)

Workaround

The REST API can be used to confirm that the correct value is set in the back-end:

/rest/api/3/configuration/timetracking/options

curl --request GET \
  --url 'https://your-domain.atlassian.net/rest/api/3/configuration/timetracking/options' \
  --user 'email@example.com:<api_token>' \
  --header 'Accept: application/json'
