[jdm]

The menu on the left side of the page at https://hanoverlibrary.ca/fees/ doesn't appear in Servo.

Now it does not render at all

I am able to get the page to render in the latest nightly build but the menu on the left side does not appear.

[nicoabie]

On macOS latest nightly build displays an empty white page.

The panic happens when we try to draw a glyph to the canvas that isn't present in the selected font: https://github.com/jrmuizel/raqote/blob/490bff22610a130ad75eb797b6bd6e3e361bbde5/src/draw_target.rs#L755

Filed jrmuizel/raqote#150.

Excellent finding, it is very interesting that it only fails on macOS
