It is possible to input work log entry less than 1 minute during workflow transition

Issue Summary

It is possible to provide work log less than 1 minute (e.g., .1 or 0.1 which equals 6 to seconds) during workflow transition. As a result Remaining Time will be decreased by 1 minute, however, work log has entry with empty timing.

View screen does not permit to enter work log less than 1 minute.

Transition/edit screen should not proceed if the inputted log work (time spent) value is less than 1.

Steps to Reproduce

1. Add "Time Tracking" field into "Edit issue" operation for a Screen Scheme for requires issue type.
2. Create issue with some time estimated (e.g. 1 Hour)
   
3. Edit issue and input "Time Spent" ".1" or "0.1"
   
4. Check Remaining Time decreased by 1 minute 
   
5. Under "Work Log" it is not showing how much time was logged 
   
6. Look as old issue view, it is showing 6 seconds logged 
    

Expected Results

Jira should not allow input less than 1 minute or round up work log to minutes.

Actual Results

Jira accepts work log values less than 1 minute via workflow transition.

Workaround

Currently the only way to avoid is to use minutes as minimal entry. When providing Time Spent use units - m = minutes, h = hours and do not use decimal.
