<select> value is not masked when maskInputOptions is turned on

[lee-userback]

RRWEB Settings:

rrwebRecord({
    maskInputOptions: {
        select: true
    }
})

HTML:

<select>
    <option selected>Item 1</option>
    <option>Item 2</option>
</select>

Bug:
When the <select> is loaded with a default selected value, the default value "Item 1" is still displayed without any masking. When I change the option to "Item 2", "Item 2" shows as blank in the replay. So it looks like there is some masking going on when the select value is changed, but the default value does not have any masking.

Expected behaviour:
The select element should show "********" instead of "Item 1".
