It’s a current limitation of the straight-line feature – it generally doesn’t start from the exact via point, but the nearest junction (e.g. with another path). It’s something I’d like to improve at some point, but it has always been the case – it hasn’t changed.

I remember using it at on not mapped bridges. That's indeed a simple task.

Thanks for the very fast answer.

For now, I have to live with it.

It’s a limitation deep in the bowels of the routing engine. It will be fixable but I haven’t worked out how yet!

Another strange result: cycle.travel/map/journey/369810

Notice unexpected direct line connection between via 1 and 2.
