Ah, apparently the problem is that Stylus can't modify the browser itself, only page content. (Response to my support request.) I did see that in the Stylus doc but didn't make the connection that these tooltips, which I think of as coming from the page content (so should be ok), are actually internal browser elements that cannot be modified.
The hunt is on for some other way to solve my tooltip problem in FF 57. "Don't update" isn't a long-term solution, after all, though "switch to a different browser" could be. I need to evaluate my browsing ecosystem both at home and at work...
Thanks for the help!
Update: Firefox has a hook for user-supplied CSS (link from the answer to my Super User question). That works in 56. Mozilla hasn't added any warnings of doom to that page, so it seems plausible that it will continue to work in 57.
