Marking where point is, does not work

[ijacquez]

Bug Write a .cs script with an error:

|XvoidX Foo() {
^
 \___ Cursor is |. Wait until flycheck-popup-tip shows up indicating an error
      and press C-space then C-e to highlight line

The end result is that the cursor moves to the end of the line (due to C-e), but doesn't mark. Disabling flycheck-popup-tip fixes this problem.

Edit

1. Moving the cursor to the left, leaving one space char "fixes" the issue.
2. Marking via C-space twice at the original position (in the diagram) "fixes" the issue.
3. Moving the cursor to the EOL (C-e) "fixes" the issue.
