@Rekkonnect ?

[Rekkonnect]

Do you have a repro for this?

[Rekkonnect]

This should have been fixed with #78173

[jasonmalinowski]

This has been fixed but note that fix isn't in 17.14; not sure if this is worth a backport since I'm still seeing it in 17.14. @CyrusNajmabadi thoughts?

[jasonmalinowski]

(assigning this to @CyrusNajmabadi as he's the helper here, no strong opinion of whether work needs to be done though)

[CyrusNajmabadi]

Yeah, let's backport this.

[CyrusNajmabadi]

Fixed with #79256
