I have a layer with polylines that intersect with polygons where I use the method intersection (Spatial filter). I want to remove those lines where bigger parts of the line is outside than inside a polygon. How should I proceed?

Does a polyline always intersect just a single polygon like the left figure? Or can a polyline intersect two or more polygons like the right figure?
I'd follow this process
- Calculate the length of the lines
- Store the geometry as an attribute
- Clip the lines with the polygons
- Calculate the length of the clipped lines inside the polygon
- Test if that length is greater than 50%
- Recreate the original geometry from the attribute stored in step 2
