Coding agent is moderately succesful picking the right branch to start a PR on

[PureWeen]

Describe the bug
This might be more an issue that I just need to prompt better, but I have an issue here dotnet/maui#31083 that I assigned copilot and wanted it to work on the net10.0 branch. I tried to prompt it in the description to start on the net10.0 branch but wasn't able to get it to work, so I eventually just used the copilot chat on github and told it to create a PR for me and that worked.

Expected behavior
Since I've articulated in github description the branch I want it to use, I was hoping it would know the branch to use.

Additional context
Here are the two PRs it created incorrectly
dotnet/maui#31084
dotnet/maui#31087

it looks like from the session it tried to find branch net10 vs net10.0
$ cd /home/runner/work/maui/maui && git branch -r | grep net10

<exited with exit code 1>

Hi @PureWeen Copilot coding agent invocation from an issue does not have the ability to work off of branches other than the default at this time.

As a workaround, you could open the same issue targeting the correct branch using the Agents page (https://github.com/copilot/agents). For example:

The ability to use other branches from the issue -> pull request flow is something that we are currently exploring.
