Redmine

At least in Redmine v5.1 and trunk, the width of the message subject field overflows its container.

This patch fixes this issue by setting max-width for the message subject field.

Here are the results after the fix.

I have tested the following:

• Does not affect the layout of the message subject field in other message forms (see screenshot below)
• Tested with Chrome and Firefox
