Two factors:

   1.  A commit of Emacs, modification-hooks might not be run in some cases:
    http://git.savannah.gnu.org/cgit/emacs.git/commit/src?id=564d811725596f15ecf543777e11504b47d2af86

   2.  In ggtags, an overlay is deleted in the overlay's modification-hooks:
    https://github.com/leoliu/ggtags/blob/eec392d2d639030c5a51bce8431f2815ad8e7bc5/ggtags.el#L2306

Deleted overlay ceases to be attached to the buffer. If the buffer of
the first overlay in the saved array doesn't match the current buffer,
then all the modification hooks will not be run in this buffer.

Thus modes that depends on modification-hooks won't work together with
ggtags-highlight-tag mode.

I think Emacs should support `delete-overlay' in modificaiton-hooks of
overlays, like ggtags.  So I report this bug.
