[0.17.53] Signal on curved rail bounding box problem

[exgen]

I was about to report the bounding box of curved rails not being symmetric, then I saw the next release and updated.
The problem is the signal on the curved rail in my 0.17.52 save which should have been disabled, remained active.

On 0.17.52 it was possible to place signal on the curve in these situations:

I was designing a square (screenshot from 0.17.53):

(Which unfortunately didn't work when rotated so I found the symmetry bug)
You can see the chain signal is still working (it’s not blinking) but when removed, it can't be placed again.

BTW, I don't remember the behavior before new changes, But I think the bounding box is a little too big.
I would assume it should be possible to place a signal in this long curve:

Thanks for the report however that's not a bug. It even visually overlaps with the other curved rail indicating it wasn't supposed to be there to begin with.

Fair enough, but the actual bug is that the signal doesn't get disabled and still works across saves. Is this intended?

It's a side effect of the change. Not worth adding in migration logic just to account for it.
