cleared manually, the statuses will continue to look like they
have media embedded.

* bundle exec i18n-tasks normalize && yarn manage:translations

* Remove ar.simple_form.hints.defaults.{display_name,note}

* Rescue when there's no extension in the remotable
Sometimes the remotable is pointing to a directory with no file
extension. Maybe it should not be expecting to identify based on
extensions to begin with, but since it's the case, it should be ready

* Fix codeclimate issue

* Check if filename is nil instead of rescueing exception
Suggestion made in the PR

* Avoid concatenation issue if filename is nil
If filename is nil, extname was undefined

* Invert condition
Address PR comments

* fix validation error (media only status)

* Incorporating review suggestions

* Reflect similar fix to OStatus side

* Fix not to include media in transaction

* Restore the limit of the number of media

* Fix not to return nil

* Remove pointer events on the entire UI when a dropdown menu is open

This prevents operations to change the location of the menu such as
scrolling.

* Fix mistake from merge
