Last Plugin Version produces an effect on the summary editing (low case)

Description

Hi, since we jumped from JIRA 6.4.11 to JIRA 7.2.6, we have a strange behaviour from the summary field. When inline-editing or editing it, the field becomes too small and case is way too small.
JIRA 7.2.6 in our test environment has the same issue.
Could you help us in fixing this, as we didn't manage to find a hint anywhere ?
Thank You
Attachment 1 is the summary in view mode, Attachement 2 is the field in edit mode.

This happens when only VertygoSLA is activated (all other plugins deactivated) and only on tickets having SLAs.

Could you help us there, as it is quite annoying for our Service Desk (they can't really see the total line of what they writing).

Thanks.

Kind Regards,

Environment
