Summary REGRESSION: Words render on top of each other when fallback font is used

See the first line in the attached test case. On the second line, there are two separate runs, but they are transposed. The third line shows the same problem with LTR override (I think for Font this is indistinguishable from visual Hebrew).

The overlapping happens only when font fallback happens (e.g. with Times as the default font), and regardless of visual-ness. The run transposition on the second line happens either way. May have to split this into two bugs.

Okay, forget about the second line in the test case (it's not a regression and I'm not sure it's a bug). This bug is about overlapping text in the first and third lines here and in a bunch of tests in fast/text. It seems to happen when font fallback happens (so you see it mostly in Hebrew) but also in other cases where an alternate font is used, such as in the small caps case of fast/text/atsui-multiple-renderers.html (not on the ATSUI side but rather on the CG side!).
