[2.1.14] Undergound belts hand-placed on ghost does not place other side automatically

[RecoverForest]

When using a blueprint with blue belts i created it using yellow belts.

When placing a yellow underground belt on a yellow underground belt ghost that has a connected output, it does not place the belt on the output automatically. However, when hand-placing a yellow one on a blue underground belt ghost, it DOES place a yellow one on both ends.

I expected the same to work when you match the colour of the blueprint.

This always happens with the belt combination mentioned.
I have not tried more permutations as I got interrupted by an unrelated crash of my pc.
