Sketcher: Some constraints can be selected with the mouse while others can't

Is there an existing issue for this?

Problem description

In the sketcher I can select some constraints to delete them but others can't be selected. In the attached screen recording I can't select the two constraints on the right side. I assume it's because they are close together

can you select them when zooming in closer so they appear with a wider gap? Please also test on the dev version: https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds

Seems like a duplicate to https://github.com/FreeCAD/FreeCAD/issues/13439

@maxwxyz On 1.0 it helps to zoom in, at some point the constraints become selectable.

1.1 shows only one of the two constraints when zoomed out but when you zoom in, it shows both and both are selectable. I think the fact that 1.1 is merging the constraints when zoomed out, is not ideal.

I was able to select/highlight all of the constraints in FC1.1dev (41365 on windows 11). I wonder if the "pick radius" has something to do with this. I have pick radius set up at 5 px.

Can't reproduce. Can it be OS-specific?
