We've read on an earlier Issue from 2011 that it's intended behavior
as well, but some people on the same Issue weren't sure:
https://code.google.com/p/chromium/issues/detail?id=71179
Chrome Help sites discuss the topic here:
https://support.google.com/chrome/answer/2693767?hl=en
Note that the Media Exceptions page doesn't explicitly say that you
can add exceptions, it only says you can deny. It does, however, point
you to the Manage Exceptions page on this topic which does say that
you can add using a button. This looks like it's just unintentionally
misleading.
After re-reading everything carefully, we assumed based on the help
article that the only way to de facto allow an exception is to click
"Allow" on a site requesting an exception that is running on HTTPS
as Chrome will only remember your preference for Media Exceptions on
HTTPS sites. It seems a bit restrictive for users who are savvy enough
to edit their own security settings deep down in the menu tree, but
security is security.

Thank you freshstart. This is exactly it. Https
means that "allow" can stick.

You add a rule by going to the site in question and then, if Media
setting is "Ask when a site wants to use a plug-in to access your
computer", it should prompt you for what to do - that will then get
set as a specific exception.
You only use Manage Exceptions to remove existing exceptions.

exceptions
Another SO answer had a workaround but it reportedly does not work anymore. Via How to allow Chrome to access my camera on localhost?
