Can't extend track/road underground from tunnel in 124.4

[Combuijs]

Is there something changed in the way we can build track or road underground?

I build a tunnel with Ctrl, so only tunnel entrance is build. In previous versions I could extend the track underground from the tunnel by going in underground modus, select the tunnel tool, select the tunnel tile, press Ctrl and draw the track I want, but nothing happens. No feedback at all, no track becomes visible, no message at all.

I use my own custom made pak, based on pak64, but nothing special in this case, should be easy reproducible with pak64. Am I doing something wrong, is the user interface changed for this case?

I also found this bug in pak128.
In my case, if the ground level is 3 higher than the tunnel base(in half-height case), I cannot extend tunnel underground. if the ground level is 2 heigher(just below the ground), I can extend it.

This only seems to happen in underground mode; sliced underground mode works fine.

Yes, I can confirm that, sliced underground mode works fine, plain underground mode does not.
