Inkscape 1.3.2 : Combining shapes and Stroke to path change the shape of some part of the new shape.
#### Summary:
An empty red square with a stroke of 10 mm combined with two straight crossed lines with the Bezier tool as chords (snapping was on) changes to a path by using of Stroke-To-Path in the Path menu. However, on the left upper corner, something weird happened, an empty tiny triangle appeared.
#### Steps to reproduce:
- Open Inkscape
- Draw an empty square and increased the stroke to 10 mm.
- Add two straight crossed lines with the Bezier tool as chords while snapping was on.
- Combined them (in Path Menu, Combine).
- Stroke to Path and now it happens.
#### What happened?
On the left upper corner, something weird happened, an empty tiny triangle appeared. and the shape and size of one of the straight line will change.
#### What should have happened?
The shape and size of all parts of the figure must be preserved as they were.
