[css-exclusions-1] Define properties animation type #10622

When generating the specification CSS Exclusions Module Level 1, errors occur:

LINE 141: The propdef for 'wrap-flow' is missing an 'Animation type' line.
LINE 359: The propdef for 'wrap-through' is missing an 'Animation type' line.

In the CSS Exclusions Module Level 1; Exclusions, the properties wrap-flow and wrap-through do not have an animation type.

At the same time in Web Animations; Animating properties it is stated that all properties must have an animation type:

Unless otherwise specified, all CSS properties are animatable. How property values combine is defined by the Animation type line in each property’s property definition table.

@cdoublev opened pull requests regarding this issue, but it's unclear what type should be applied to wrap-flow and wrap-through.
