Tabbing through new issue and choosing (enter) label and going back to edit pane leaves return in labels field.

Summary

In form for new issue when i use tab key to go to labels, choose a label via Enter, and go back to issue description with shift+tab, the return is still in labels menu and is activates/deactivates last label (while caret is visible in description part of form).

Steps to reproduce

New issue.
Tab to Labels.
Type label name to autocomplete.
Choose first label by pressing enter.
Shift+tab back to description area.
Press enter.

What is the current bug behavior?

The enter key toggles last label instead making new line in description/

What is the expected correct behavior?

The enter should go back where the caret is (it should follow tabbing through items of form)
