#### Summary:
When using a multiple click tool (e.g. Bezier curve) and snapping to a guideline, the cursor will often change from the Bezier tool to a 'select the guideline' tool. Instead of adding another point to the Bezier curve, clicking will select/move the guideline.
This was not the case in Inkscape 1.0.2. See attached screen shots.
#### Steps to reproduce:
- open Inkscape
- create a guideline
- choose the Bezier tool
- make one point off the guideline
- try to create another point **on** the guideline. Move the cursor around on the guideline to see that the Bezier tool often changes into a **select guideline** tool.
#### What happened?
When the **hand** icon appears clicking will select the guideline.
#### What should have happened?
The 'hand' icon should not appear -- the Bezier tool / icon should remain active.
Clicking should add a point on the guideline, not select the guideline.
