Issue Summary

When a repository hook (such as the "Yet Another Commit Checker" / YACC plugin) vetoes an action (e.g., a file edit via the UI), the rejection message displayed in the Bitbucket UI incorrectly renders HTML entities. For example, an apostrophe in the word "doesn't" is displayed as doesn&#39 ;t.

Steps to Reproduce

1. Install Bitbucket Data Center 10.2.2 or 10.2.3.
2. Enable a repository hook (e.g., YACC) that validates commit messages. ('Commit Message Regex' that requires that commit messages match this regular expression. for a repository)
3. Attempt to edit a file directly in the Bitbucket UI and save it, triggering the hook rejection.
4. The commit is rejected and the following message is displayed on the UI - *commit message doesn&#39 ;t match regex: *

Expected Results

The UI should display the message as "commit message doesn't match regex:"

Actual Results

The UI displays - 'commit message doesn't match regex:'

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
