Please assist,

Which of the following can I report as a legit bug in a website:
and if it is,
what is the severity?
and id it functional or technical?

1. A link in a page that works with regular left click
but when you open in new tab like this
right click->open in new tab or Ctrl click
it opens an empty page (about: blank)
(the reason is because it is a dynamic page using javascript to go from section to section)

2. A form field for email that lets you make a mistake at the end of the mail.
for example, somemail@mail.com@mistake@mistake.mistake
as long as it has something@something.something it approves whatever you write after it.

Thank you.
