Summary

Remaining time is set to 0 if there is work logged before the issue was estimated.

Steps to Reproduce

1. Make sure JIRA legacy mode is disabled in Time Tracking Configuration (this is set by default)
2. Create an issue
3. Log work to an issue
4. Add Original Estimation for the issue

Expected Results

Remaining Time changes accordingly to the work logged

Actual Results

Remaining Time is set to 0 when work is logged
Remaining Time is not changed when estimation is edited

Notes

It is possible to manually edit the Remaining field to a specific value and further logged work will be extracted from this value.

Workaround

Estimate the issue first and then log work on it
