Changes
Added a warning when passing a non-array to
Astro.slots.render
as it can lead to weird behaviour since it technically will work with things that are not arrays but are iterable (ex: a string). Also updated the JSDoc comment with how to use the second argumentFix #3562
Testing
Tested manually. We have tests using this function already
Docs
Updated JSDoc with information about this and will get in contact with docs to document this
