Element modifiers don't work with multiple lines

[jakesjews]

div.some-class{{did-insert this.onInsert}}

works but

div.some-class [
  {{did-insert this.onInsert}}
]

does not.

As an alternative I tried

div{{did-insert this.onInsert}} [
  class="some-class"
]

but that did't work either.

I also tried

div.some-class [
  (did-insert this.onInsert)
]

but that didn't work either
