Mark Stacey ffb36f95ef Fix yarn build styles:dev (#9709) ... The `styles:dev` step of the development build was broken in #9568 when the `lockdown()` function from SES was introduced. One of the effects of `lockdown()` is preventing the use of `RegExp.lastMatch`, which is relied upon by `postcss` for parsing inline sourcemaps. This problem has been worked around by re-arranging the build pipeline for styles. Firstly, the `autoprefixer` stage was moved _before_ sourcemaps were generated. Its placement _after_ sourcemaps was a mistake in the first place - it should have always been before they were written, so that the sourcemaps could keep track of the changes made by `autoprefixer`. Second, the `-rtl` sourcemap generation was moved to a separate build pipeline. The `rtl` stage also uses `postcss`, and it must come after the sourcemaps are written for the non-RTL styles, so splitting it into a separate build was the only way to avoid passing in inline sourcemaps. This does make the build slightly slower, but it also decreases the size of the RTL sourcemaps dramatically.		2020-10-25 16:25:24 -02:30
