`addHTMLLengthToStyle()` is using CSS parser to get the values. We should reuse `parseHTMLDimension()` here.

Hi,
I think this patch is ready for review now:)
It applies HTMLDimension to other length parsing scenarios.
Please take a look, thanks!

Typo here in isMultiLengh

Not thrilled with the word "configs" here. I think the function name doesn’t have to change just because we have three more arguments; it can just be an overload. Think of the arguments as having default values.

These all can and should be private instead of protected. Also not sure that these options are best represented as three separate booleans, but if we make that private it’s easy to change it later.

This function should take a StringView, not a const String&.

These functions should take StringView, not const String&.
