> Any other opinions on this topic? when the cursor (mouse cursor, not text caret) is hovering some text that's been either rotated by a transform, or shaped along a path, should this visual orientation affect the choice of a vertical / horizontal cursor (MAY? MUST?) or should we limit the influence to the writing mode (and associated) properties?

I think the spec should say it must be perpendicular to the baseline, as determined by the writing mode, and that transforms and any other properties that rotate the text, such as text along a path, may (should?) also rotate the cursor in order to maintain this perpendicularity.
