In the New Issue View, entering a value in a Date Time Picker field and then hitting Tab results in the value not being saved

Issue Summary

In the New Issue View, entering a value in a Date Time Picker field and then hitting Tab results in the field's newly-entered value not being saved. Clicking out of the field also results in the same.

Steps to Reproduce

1. Enter a value, typing in a time in a Date Time Picker field (i.e. do not click a time from the dropdown list, you have to type it in manually). This can be a custom field or, for example, the Time tracking Date started field:
   
2. Hit Tab
3. Note that neither the date nor time value has been saved.

Comparison
The above issue does not occur in the following cases (i.e. in the following scenarios, hitting Tab does result in the value of the field being saved):

• If you click a time value from the dropdown rather than typing it in, and then hit Tab
• If you hit Enter instead of Tab in Step 2
• If you are using a Date Picker instead of a Date Time Picker

Expected Results

Consistent behavior from hitting Tab after filling in a field and newly-entered values being saved.

Actual Results

Hitting Tab does not alwats save the value of the field you have just entered. It fails rather quietly so it is easy to miss that your newly-entered value has not saved.

Workaround

Make sure to hit Enter instead of Tab after filling in a Date Time Picker
