SvelteSet.has, SvelteMap.get and SvelteMap.has aren't fine grain when parameter is not in the object

[Thiagolino8]

Describe the bug

When using the .get and .has methods, if the searched value does not exist within the object, the effect is triggered even if the returned value has not changed (false or undefined)
When the searched value exists within the object, the effect is triggered only when the result changes

Reproduction

While foo doesn't exist within the set, the hasFoo function is triggered with each new task created
After the foo task is created, the hasFoo function is no longer triggered
repl

Logs

System Info

running Svelte compiler version 5.40.1

Severity

annoyance

Unfortunately, it either causes memory leaks on the keys or slows down the map by up to ~15 times.
