In this module: local p = {} function p.main(frame) local builder = mw.html.create('span'):css('opacity', 0) return tostring(builder) end return p The call to p.main() results in the following script error: Lua error: bad argument #1 to 'gsub' (string expected, got number). Backtrace: [C]: in function "v" mw.ustring.lua:61: ? (tail call): ? mw.html.lua:113: in function "_build" mw.html.lua:51: ? [C]: in function "tostring" Module:Sandbox/Jackmcbarn:5: in function "chunk" mw.lua:478: ?
Not actually a bug in mw.html, it's that mw.ustring isn't autoconverting numbers where Lua's standard string library does.

Well, it's partially both. There's other ways to cause this that make it fail in places other than ustring.
