[1.1.87] Reverse Rotate often doesn't work when placing signals and stations on positions shared by two different tracks

[Hell_Diguner]

When Rails cross, merge, or split, some placement indicators for rail entities (Train Stop, Rail Signal, Rail Chain Signal) can be valid for two different tracks. We can use the Rotate key to switch between the different options at these positions, however, Reverse Rotate usually does not work.

Reverse Rotate appears to only work in the specific case of rotating a Train Stop 90 degrees counter-clockwise. Unlike Rotate, it will not perform a 270 degree rotation back to the previous orientation. And unlike Rotate, Reverse Rotate does not work with Rail or Chain Signals that are hovering over positions with multiple options.

It *might* be relevant that I have rebound reverse rotate to W and Shift+W (and rotate to R and Shift+R). I use an ESDF control scheme, which is like taking WASD and shifting everything to the right by one key.
