emacs version is 27.2 (Installed using dnf on fedora 35 system)
test file: https://github.com/torvalds/linux/blob/v5.16/kernel/events/core.c
Step1: emacs -Q kernel/events/core.c
Step2: eval "(font-lock-mode 0)"
Step3: eval "(highlight-regexp "static")"
The "static" keyword at the end of the file is not highlighted.

In Emacs 28 the default value of `hi-lock-highlight-range'
was increased from 200000 to 2000000.
