Possible bug: enlist and join on no field or empty fields

[Mohammad]

• In https://tiddlywiki.com/prerelease/
• Create a new tiddler
• Put the below wikitext inside its text field

<a href={{!!url}} target="_blank">

<$list filter="[enlist{!!keywords}join[, ]]" variable=item><$text text=<<item>> /></$list>

</a>

• Save.

Why Internal JavaScript Error is appeared?

If you add url and keywords field but keep them empty, the red popup error window appears again!

That seems like a bug. It's not just the pre-release. It breaks in 5.1.21 as well.
