The mobile web site used to support the zoom gesture, which I often use to be able to see images and interact with comments. In the last few days this has stopped working for me. I'm using Chrome (51.0.2704.81) on Android (4.4.4).
I'm not talking about automatic zooming that I'm told used to be built into on iOS. I'm talking about user-initiated zoom, which used to work and now does not.
I'm aware of this similar question, which is tagged ios. That seems to be about the app. My issue is with the mobile web site.
