Unfortunately the new hammer.js functionality wasn't correctly tested and didn't work across devices and browsers, as such, it's best to revert PR #6944 until we can revisit this functionality and make it work across all devices and browsers that are supported by Mastodon.
This reverts commit 5021c4e9ca.
