@sandipb if you add "Fix #14811" to the description it should auto close your bug when it is merged

I was not sure which description you meant :) I updated the pull request description. Or do you think the git commit itself should have it in the description?

[phlax]

either should work - the pr is probs best so it is obvious to reviewers
