The assertions have been replaced with a warning.  Loading about:home now produces a stream of warnings, followed by a panic in Servo code:

thread 'StyleWorker worker 1/3' panicked at 'Calling previous_styles without having gathered it', /home/mbrubeck/src/mozilla-central/servo/components/style/data.rs:167

This no longer asserts or crashes.
