Location triangle doesn't cover entire city

[thibaultmol]

I'm submitting a (feature request)

Brief Description

When I enter the name of a town (in my example Ruiselede, Belgium). The triangle that osmcha decides to make doesn't actually cover all of Ruiselede. While that's exactly what I want to do.
I have read that filterting by actual town name in the changesets isn't possible so we have to use bbox. But the triangle it suggests just doesn't cover all of Ruisleede.

What is the motivation / use case for this feature?

I want to keep an eye on all edits of my town, now it ignores edits at the edges of it.

What is the current behaviour, (attach relevant screenshots) ?

This is what the actual boundery is like:

What is the expected behaviour ?

Make the triangle (or make it an option) cover the entire boundary of the city.

(estimation of osmcha shows me and the bigger triangle is what I want to see

When does this occur ?

How do we replicate the issue ?

1.Open the filter menu and put in city/town for the location
