On "zoom to problem" in "Crossing boundaries" validator report zoom to one of crossing points, not bounding box of boundaries

[mkoniecz]

What steps will reproduce the problem?

1. run validator
2. find two huge crossing boundaries
3. select "zoom to problem"

What is the expected result?

I get zoomed to problem (crossing point of two boundaries)

What happens instead?

I get zoomed to boundary extend ( ​https://www.openstreetmap.org/way/231994686 ​https://www.openstreetmap.org/way/232003133 )

Please provide any additional information below. Attach a screenshot if possible.

It would be also nice to mark location of the currently selected validator issue (pulsing green point? arrow? green target sign pointing at it?)

Hmm, the zoom to shows the area where they overlap. The two boundaries in your example mostly overlap, so I don't see what else JOSM could do. Maybe you think about a new function like "zoom to where they differ" ?

[mkoniecz]

So this validator rule reports both crossing and overlapping boundaries, not only crossing ones?

[GerdP]

The validator produces two warnings, one with crossing boundaries, one with overlapping ways.
The 2nd one zooms to a smaller area. Maybe this helps you?

It helped in this case, thanks! I will report it again if I encounter a better example.
