1 On the line

#define X 0

place the caret to immediate right of X and press SHIFT-LeftArrow to select X, leaving caret left of X.

2 Type Y

3 Press CTRL+Z (Undo).

Expected: text, selection and caret restored.
Observed: text and selection restored, but caret moved to right of X.

Note: Undo is undocumented (as far as I can tell) and so unspecified behaviour.
