[CI] IndicesOptionsTests.testSerialization fails reproducible on master #30648
Description
While debugging another issue, this test fails reliably for me on osx and linux with this seed.
Note, this issue did happen on CI, only on my local machines, thus no link to CI.

I have no real idea where to sort this under, so I picked Core/Core, feel free to change anytime. @javanna this might be one for you?
