DOMRect normalizes NaN and negative zero to zero #58240

Description

@OskarEichler

Description

The shared numeric conversion used by DOMRectReadOnly construction and mutable DOMRect setters defaults all falsy values to 0. Valid NaN is therefore replaced with zero and -0 loses its sign.

Expected behavior

Only omitted/nullish optional values should receive the zero default. Supplied numeric values should undergo normal Number conversion while preserving NaN and signed zero.
