… scope Summary: Right now, if something like `CSSColor` accepted a function notation block (e.g. for `rgb()` syntax), it is given a syntax parser which may extend beyond the scope of the current function block. This is confusing, but also problematic for the `CSSSyntaxParser` block visiting logic to validate a correct scope exit. This change makes it so that the `CSSSyntaxParser` passsed to `CSSDataTypeParser` for function and simple blocks is limited to the syntax within the given block. This prevents extra visiblity beyond the block we are trying to parse, and allows the function/simple block visitor to reliably fail parsing if the block is not correctly terminated, or there are unconsumed component values within the block not handled by the data type parser. Changelog: [Internal] Differential Revision: D68340127
Summary:
Must function notations do not require delimiting commas, with color function "legacy" syntax being an exception.
E.g.
```
rgb() = [ <legacy-rgb-syntax> | <modern-rgb-syntax> ]
rgba() = [ <legacy-rgba-syntax> | <modern-rgba-syntax> ]
<legacy-rgb-syntax> = rgb( <percentage>#{3} , <alpha-value>? ) |
rgb( <number>#{3} , <alpha-value>? )
<legacy-rgba-syntax> = rgba( <percentage>#{3} , <alpha-value>? ) |
rgba( <number>#{3} , <alpha-value>? )
<modern-rgb-syntax> = rgb(
[ <number> | <percentage> | none]{3}
[ / [<alpha-value> | none] ]? )
<modern-rgba-syntax> = rgba(
[ <number> | <percentage> | none]{3}
[ / [<alpha-value> | none] ]? )
```
Theoretically, this should mean an expression like `rgb(1, 2 0)`, which mixes both comma and whitespace delimeters would be malformed, but both Chrome, and RN's existing `normalize-color` package support this, so to make this pattern easier, we add the ability to scan based on using either whitespace or comma as component value delimeter.
