Description

When we updated fluentassertions to the latest version 5.5.0, we encountered an issue with the BeEquivalentTo assertion.
When we compare a list of objects, which contains another list with the same items but different order, the test will fail, even though strict ordering is disabled.

Repro

To reproduce this issue, I've created a repro repo which can be found here:
https://github.com/michaelestermann/OrderingRepro

Expected behavior:

Expected behaviour would be, that the lists are the same, even though the order of the lists are not the same.

Actual behavior:

Since the update, the test fails, because of the of the mismatching ordering of the list

Versions

We use the latest FluentAssertions 5.5.0 along with .NET Core SDK 2.1.500
