Commit title when squashing one commit

At the moment, when making a PR with a single commit, even though we use the squash option, the title of the PR is not used as title of the squash. I’m guessing that, since there’s one commit, Github does not perform a squash (therefore there’s no commit message).

Could you please change that and make the behavior consistent? Now there’s:

1 commit → use commit
N commits → use PR title

We’re big boys, if we press the squash button we know what we want to do with that. It should be:

1 commit → use PR title
N commits → use PR title

PS: Gitlab and Bitbucket does it.
