Constant 'Dependency could not be updated or already up to date!' on merged MRs

We use this project with PHP projects, normally daily, where there can be a number of updates added within the same day for different dependencies.

After being reviewed, these often get merged quite quickly (less than a minute between them).

Dependabot then tries to update all the other merge requests, including the ones that have just been merged, giving us:

Dependency could not be updated or already up to date!

My guess is that the job that fires when one of them is merged isn't looking at the real-time state of the other merge requests
