Those spaces are actually a Unicode chars for non-displayable spaces. They are unfortunate byproduct of the tagify we use for the visual expressions and the last version of it.
We try to clean them up but seems like we missed a few cases.
So could you please specify after which actions exactly those invisible spaces pppup?
its easy enough now to just delete the ““ and then re-add them. Now that I know what to look for. It doesn’t affect the code at all, it just gives me error messages in the browser console.
