RenderTextHarfBuzzTest, HarfBuzz_BreakRunsByEmoji fails on Android.

Early versions of macOS provide a tofu glyph for the variation selector. This probably happens on Android as well.

From the error message below, it seems one extra space is used. That extra space might be for a tofu glyph.

However, when I visit the following URL on Clank, there's no tofu glyph.
