...
5. Let entries be the List that is the value of M’s [[WeakMapData]] internal
slot.
6. If Type(key) is not Object, return false.
7. Repeat for each Record {[[key]], [[value]]} p that is an element of
entries,
a. If p.[[key]] is not empty and SameValue(p.[[key]], key) is true, then
i. Set p.[[key]] to empty.
ii. Set p.[[value]] to empty.
iii. Return true.
