URL parser's algorithm correctly reports as valid:
http://[::1.2.3.4]
But slightly modified and invalid URLs are reported as valid:
http://[::1.2.3.]
http://[::1.2.]
http://[::1.]
In the 10 step's 7 substep last '.' is skipped (there no failure at 4 substep) and, as EOF code point is reached, after 9 supstep the 10 step ends.
Similarly also isn't reported as invalid:
http://[::1.2.3.4x]
In the 7 substep 'x' is skipped (this character is not checked, so there can be any non ASCII digit), EOF code point is reached so no failure at 8 substep and after 9 substep the 10 step ends.
These URLs I also checked with Live URL Viewer and rust-url: the same problem.
