On auto merge, merge commit overwrites change titles

[shusak]

When I have the merge config set to merge the PR on all approvals, the merge that results overwrites the PR's change title such that if I have tags in my PR title that are needed by my CI/CD process, then those tags are lost.

We use tagging in the PR title to signify additional things the build should do for that PR -> like increment version numbers, tagging, issue resolution, etc.

Checks-out breaks this functionality when merge is set to enabled.

so either checks-out should append to that or provide an option to not do that.

Example:

My PR Title:
[MAJOR] This adds breaking functionality

Checks-out merges with change title:

Merged by checks-out
Approved by:
<person>

I would expect it to be:

[MAJOR] This adds breaking functionality

Merged by checks-out
Approved by:
<person>
