Any reason not to target delivery? |
|
@neilcsmith-net no real one. I was not planning to get this into 17. It is not a regression and exists since a long time. I can rebase it onto delivery though. |
|
I'll leave it up to you. Seems a low risk fix for an annoyance? Will sync for 17-rc3 tomorrow if you do want it in. |

@neilcsmith-net as suggested I rebased, did a quick smoke test locally, force pushed and tests are green. I retargeted this to delivery. If still fine, it would be nice to get it in. Thank you. |
