Traversing map with complex key does not work as it should

[stevenwdv]

Describe the bug
Traversing a map with complex keys does not work as it should.
E.g. overriding a map key with an alias key and then traversing gives the wrong value.
And keys may match when they should not.

Version of yq: 4.45.4
Operating system: linux
Installed via: binary release

Commands

# Alias key does not overwrite
echo '{k: &k a, a: 1, *k : 2}' | yq '.a'
#Actual: 1
#Expected: 2

# Complex keys are all treated the same
echo '{["I am not the key you are looking for"]: 42}' | yq '.[{"wait": "what"}]'
#Actual: 42
#Expected: null

# And a merge anchor test for when the case above is fixed
echo '{m: &m {v: 37}, {v: 37}: 1, {<<: *m}: 2, [idk]: 3}' | yq '.[{"v": 37}]'
#Actual: 3
#Expected: 2

Additional context
For alias keys (the first test case), explode(.).a does work as expected (returns 2).
