[non-unique] IDs contain spaces on product multivariants

[man.of.earth]

Hello,

I noticed that in displaying product multivariants as radio buttons - product with child-products (I don't know about list elements of other ones) with custom labels that contain spaces, the IDs generated contain spaces, which makes the page to not validate:

Code Select Expand

Also, in browse views, when multiple products with children are shown with the same variants names (standard sizes, for example - see here: https://www.proxima-mundi.ro/printuri-pe-canvas-foto-n ), there are generated multiple non-unique IDs with the same name, which makes that selection of a certain variant to not be made correctly (i.e. you select one variant for one product, and it is selected that variant, but from another product ).

I think a good idea to generate unique IDs would be simply product_id (i.e. product_78), or maybe there is another even simpler solution.
