The CSS Box Alignment spec changed the syntax of overflow alignment so that the value 'true' has been renamed to 'unsafe'. There is no change in the behavior of the old keyword, just a syntax change, which affects just parsing and computed style logic. diff: https://hg.csswg.org/drafts/rev/f34a2a8b8177
This bug would need merging the patch for the blink's issue 1497403002.
