More problems in diagonal letters | wght 200 | wdth 33 | opsz 48

The problems mentioned in https://github.com/googlefonts/roboto-flex/issues/315 become more visible with `wght` 200, `wdth` 33, `opsz` 48 when I reduce `YTLC` to something like 435 and `YTUC` to something like 565.

```
.my-text {
font-feature-settings: "rvrn" 1;
font-variation-settings: "wght" 200, "wdth" 33, "opsz" 48, "GRAD" 0, "slnt" 0, "XTRA" 468, "XOPQ" 96, "YOPQ" 79, "YTLC" 435, "YTUC" 565, "YTAS" 750, "YTDE" -203, "YTFI" 738;
}
```

Start by reproducing issue #315 and this report using the supplied CSS settings for wght 200, wdth 33, and opsz 48, then compare the attached video with the current font output. No source file or test is named; done means the diagonal-letter problems are resolved at the reported YTLC and YTUC values.
