Imported file contains invisible objects that prevent boolean operations when selected.
- Open file

- select all 3 objects in layers ( one is a single node object so its almost invisible)
- path -union
**what happend**
Nothing
Because there is object with single node (this is probably created outside of inkscape but we should still handle this)
**what should happen**
single point should be merged/ deleted / ignored / handled in bool operations
#### Version info
