Thanks for the report, but please ask for help on the forum!

The is(":visible") selector does not check for the "visibility" property, which just deals truly with opacity, but rather checks for the "display" property.

The reason it works for div and not input is that a div that has visibility hidden and no content truly has no dimensions and is therefore effectively hidden, but that is not true of inputs.
