Fix WGLMakie nan error

[ffreyer]

Description

Probably supersedes #4727

While merging #4742 I ran into an issue where Axis3 would stop working when rotated in vscode. In the Browser this produces the same chain of errors as #4727. The "stack trace" of this issue is:

• Plane produces a NaN vector from normalize(Vec3f(0))
• while handling an edge case in to_clip_space
• which is called in lines
• which come from the Axis3 background poly plots

Type of change

• Bug fix (non-breaking change which fixes an issue)

Checklist

• Added an entry in CHANGELOG.md (for new features and breaking changes)
• Added or changed relevant sections in the documentation
• Added unit tests for new algorithms, conversion methods, etc.
• Added reference image tests for new plotting functions, recipes, visual options, etc.
