1.3.7 bug: cannot undo changes to global guidelines

In 1.3.7 changes to global guidelines (position and angle) are not affected by undo.

I know this but do not have a solution for now.

Is it possible to lock the guidelines? Since there is no undo…
I keep moving them by mistake… A lock option would fix it.

Glyphs 2.0 has a lock option for guidelines.
