"ManyManyThrough cannot mismatch Versioning between join class and related class"

https://github.com/symbiote/silverstripe-gridfieldextensions/blob/3.2.1/src/GridFieldOrderableRows.php#L604-L609, introduced in #260

I don’t see any reason for this exception to exist - if we’re dealing with an MMTL, we’re updating the sort on the join record and not touching the related record at all. Whether the related record is versioned or not doesn’t matter here, as we’re not inspecting or updating it. If I remove the exception, everything works as expected.

cc @NightJar, do you remember why this was added? 😁

Short answer: Because versioning does my head in.
Long answer: Let me get back to you... ;p

I'm pretty sure there was a reason, but it may not be as valid as I thought due to the short answer here 😉
I'll need to regain context, and I'm a bit busy for that yak shave just now sorry!

I’ve prepared PR #283 for when you get the chance :D

Cool, I'll look later too.

Long story short is that I believe it'll be to do with user expectations, rather than what is actually possible.
