Opening a link to a specific message of a Task (of the form /T12345#123456) doesn't scroll anymore to the anchor of the message on Chrome 55.
I was able to reproduce this both on Mac OS and Linux. On Linux I had Chrome 54 and it was working fine but after upgrading to Chrome 55 it stopped working.
Link to anchors on other websites that I've tried are still working as usual on Chrome 55, hence I'm assuming that this is an issue related to Phabricator and not Chrome 55, but it might be instead an issue with Chrome itself.
See for example a link to a task message in this installation too: T11953#202672
