Re: [NTG-context] underbraces get progressively more misaligned (w/ minimal example)

I've been finding many unexplained 0.5pt or so differences, which may be related to the underbrace problem. ... What I keep finding is that pages long after where I make a small change somehow get changed, with roughly one-pixel shifts to parts of the page.

These small shifts were also caused by the underbrace luatex bug (these pages all had underbraces on them)---many birds with one stone. -Sanjoy
