Transect only goes straight, no hover line

[condwanaland]

When trying to add a transect line, I'm noticing three issues

1. The hover line where the mouse position is does not show
2. The transect only goes straight - its not angled if I click somewhere on the sides
3. If I do click somewhere on the sides, the transect ends at a line that runs perpendicular to the transect itself.

I have a gif here showing the issues
