revert: fix(a): prevent Opera from incorrectly navigating on link click

This reverts commit c81d8176cc55cd15acae05259ead73f90a01f0b7.

This commit causes several issues (#1651, #1674, #1662) and doesn't even
contain a test that proves that anything on Opera got actually fixed.

If the original Opera resurfaces, we'll fix it properly.
