🤖 This is an automatic issue report for Web IDL syntax error. 🤖

webidl2.js says:

Syntax error at line 6 in web-animations-2,15, since `interface AnimationTrigger`:
 CSSKeywordValue or DOMString) rangeStart = "normal";
                                          ^

Error: Unterminated attribute, expected ;

Please file an issue at https://github.com/saschanaz/webidl-updater/issues/new if you think this is invalid or should be enhanced.

I suspect the intent of the change was to set default values for the attributes. Default values are not allowed in interface attributes in Web IDL, only for dictionary members.

[tidoust]

Also note that, even without the default value, the definition of the attribute remains invalid for the same reason as that noted in
#9355 (comment): "dictionaries aren't allowed as attribute types"

Thanks! I'll push a fix

[ydaniv]

I think this should do as a fix: #11630

[tidoust]

Oh, failed to notice, but another IDL hiccup will appear once you fix the other ones: a nullable union cannot include a dictionary type, see https://webidl.spec.whatwg.org/#idl-nullable-type

That will happen because dictionary members in AnimationTriggerOptions are defined with a ?.

[ydaniv]

Fixed.
