Fluid field conditional to check existence of field fails

[robinsowell]

EE 7.2.13 - note, user reports same conditional DID work in EE 6.

Say you have a fluid field named 'my_fluid'. In v6

{if my_fluid == ''} Nothing to see here {/if}

Worked. In the current version, it doesn't.

{if ! my_fluid}

That does work, but I don't think we want breaking behavior between 6 and 7 on something like that, and I'd expect it to work like other fields in any case.

This is not related to ExpressionEngine version, but to PHP version.

With PHP 7.4, both conditionals work. With PHP 8.1, only the second condtional works.

We also has same issue with Grid (can't find issue for that, but it has been reported several times)
