Potential Problems With The Approach

Test plan

@WoH before I go further with this, could you quickly take a look and confirm whether the test I added is indeed the desired behavior? The test is currently failing (but it used to work in 5.1.1), and I'd like to try and contribute a fix once I get your confirmation

[WoH]

Yeah. Nullable and x-nullable, but the prop should be required. That's correct

[WoH]

Thanks for taking a look into that

@WoH I was able to track down that https://github.com/lukeautry/tsoa/pull/1498 was the change which broke this (the test passes on the commit prior), but I haven't been able to figure out the right way to fix it yet.
