It's because ggtags.el enables the major mode from the actual file in this
temp " *Code-Fontify*" buffer by calling (funcall mode) in
ggtags-fontify-code.
And in my case, the verilog-mode is setting the write-contents-hooks (old
name of write-contents-functions)[1].
Looking at ggtags.el, I also wonder why the buffer survives the call to

I will start this discussion on the ggtags.el repo. Thanks.
