Difference in assets shown for read-only account depending on the import method (address vs UNS)

[michalinacienciala]

1. I've imported 0x208e94d5661a73360d9387D3Ca169e5c130090cD read-only account (it's the bnbspider.crypto's address). 4 NFTs and a number of various tokes loaded up.
2. I removed the account from the wallet
3. I've imported bnbspider.crypto again (this time using UNS, not the address). Only 1 NFT shown and only ETH visible on the token list.

I initially thought this is caused by the re-import of the same account after removing, but I did aanother test - I imported the 0x208e94d5661a73360d9387D3Ca169e5c130090cD on fresh installation and bnbspider.crypto on fresh installatinon.
After importing 0x208e94d5661a73360d9387D3Ca169e5c130090cD all the assets and NFTs loaded very quickly.
After importing bnbspider.crypto I only got the ETH asset and one NFT.
I've repeated ths test for this particular account several times and always got these discrepancies in assets. The asset list for bnbspider.crypto did not update in the future (after waiting over 10 min).

I did a similar test with other read only addresses and ENSs/UNSs and could not replicate. So I suspect this may be caused by some historical data saved in my browser.
