Card creation fails when pressing 'Enter' in a Labels system/custom field

Steps to reproduce:
1) Add a label field to the card view on any issue type
2) add all required fields on the card
3) move to the labels field and type in some labels, new or existing
4) press enter

Pressing enter submits the New Card dialog but the card is not created.

Expected behaviour:

• When I press enter in any field on the New Card dialog there is no action
• When I press enter in the Labels field on the New Card dialog the form should not be submitted
