Unexpected behavior for the allbefore:include operator

[c pa]

Good day,

This behavior requires me to add a +[first[]] block and then a +[rest[]] block all over the place

Code being executed

    <$list filter="one two three four" variable="component">
        <$count filter="one two three +[allbefore:include<component>]" />
    </$list>

Expected results

    1 2 3 4

Actual results

    0 2 3 4

Discussion: I'm using $count allbefore in order to generate index number within lists (Very useful as discussed in other posts)

No solution but for clarification, the case can be minimized to:

<$count filter="foo +[allbefore:include[foo]]"/>

Result:0

Expected:1
