Bug: Bars with zero value are not able to render labels

[tigerabrodi]

Please 🫠 , don't close this issue like done with #2172.

It seems like the issue in #874 is back. I am unable to render a zero above the bar when it's value is 0. The fields with value 0 get excluded completely. I'd assume something like !{the value} is done in the source which means if the value is the number 0, the expression !0 results in true.

What do I expect?

Explicitly check if undefined, otherwise if the value number 0, it should be totally fine to include the field!

Looking in the source code, the function filterZerosIfLog in the file packages/bar/src/compute/stacked.ts seems suspicious. But I'd need to take a deeper look to properly fix this.

Pinging people who had this issue in the past, and it doesn't seem to be resolved yet, or it's back!
