It was recently pointed out to me that the tabindex attributes all over the place in the bbPress plugin are causing accessibility problems for users who are blind or due to mobility, navigate my website using the tab key. Disrupting the tab sequence of a page is almost never an OK solution on a site, as it creates a confusing and unpredictable navigation, and that is what bbPress is doing by setting its own tabindex attributes.
For my own site, I have copied all the bbPress templates into my child theme and am working on removing all the tabindex attributes manually. This, however, seems like a very poor solution to a pretty big accessibility problem. Can you just remove all the tabindexes, or at minimum, offer an option in the plugin to toggle tabindex attributes off?
