When trying to access a character on a string buffer object via `:[]`, if the object being accessed currently returns `html_safe?` as true,
we used to set `@html_safe` variable as true on new object created. When doing something like
x = 'Hello'.html_safe
x[/a/, 1]
would throw an error on ruby 2.2, since when nothign gets matched nil is returned by the code and it tries to set `@html_safe` value to true,
which would error since starting 2.2 nil is frozen.
This change adds a safety net to avoid setting `@html_safe = true` on frozen objects.
Fixes #18235
