The `PaintWorklet` specification claims that [`drawImage()`](https://drafts.css-houdini.org/css-paint-api-1/#example-2) is possible. However a `TypeError` is thrown when passing `url()` ([CSSImageValue](https://drafts.css-houdini.org/css-typed-om-1/#imagevalue-objects)) function to `drawImage()` (https://github.com/w3c/css-houdini-drafts/issues/877#issuecomment-487727155) `TypeError: Failed to execute 'drawImage' on 'PaintRenderingContext2D': The provided...
If I define a custom property explicitly with the `@property` at-rule by using a straightfoward color value for `initial-value`, it works. Working example below: ```CSS @property --my-color1 { syntax: "";...
Currently, grammars like `syntax:"auto | --mything"` are not allowed, since we don't handle HYPHEN-MINUS during "consume a syntax component". This was likely an oversight when it was initially written. Note:...
Also, fix the code sample where the constraints variable where redefined. I’m taking this opportunity to ask if there’s a place where I can ask questions about the Layout API....
In 3d51716987994673b9f24fbe5fa3bf94e0447781, [apply the percent hint](https://drafts.css-houdini.org/css-typed-om-1/#apply-the-percent-hint) was modified, in part to add a step 4 which returns `type`. However, none of the callers of this algorithm make use of the...
The current CSS Typed OM spec specifies [StylePropertyMapReadOnly's](https://drafts.css-houdini.org/css-typed-om-1/#stylepropertymapreadonly) [`get()`](https://drafts.css-houdini.org/css-typed-om-1/#dom-stylepropertymapreadonly-get) as: ``` (undefined or CSSStyleValue) get(USVString property); ``` However, the WTP tests for this all seem to expect null to be...
The [`syntax` descriptor](https://drafts.css-houdini.org/css-properties-values-api-1/#the-syntax-descriptor) could now be defined with a "naked" value matching [``](https://drafts.csswg.org/css-values-5/#css-syntax). When declared as a ``, its value would be [parsed](https://drafts.csswg.org/css-syntax-3/#css-parse-something-according-to-a-css-grammar) against `` instead of calling [consume a...
The [spec](https://drafts.css-houdini.org/css-properties-values-api-1/#initial-value-descriptor) wants `@property` to be invalid when `syntax` is not `*` and `initial-value` is a computationally dependent value. In current version of Chrome and FF, `@property` is valid with...
There is this note about [computationally independent](https://drafts.css-houdini.org/css-properties-values-api-1/#computationally-independent) values: > [...] `3em` is not computationally independent [...]. **Neither is a value with a `var()` function**, because it relies on the value...
