Handlebars: newline in an attribute incorrectly rendered as [object Object]

As reported in jgwhite#1 (comment)

Prettier 2.0.5
Playground link

Input:

<Foo arg="
"/>

Output:

<Foo arg="[object Object]" />

Expected behavior:

<Foo arg="
" />

Seems to be fixed in Prettier 2.2.0. At least the Playground link is showing expected output for me.

Interesting, ok, closing.

@fisker do you know why this doesn't happen anymore if my PR hasn't gone in yet?

I think this not resolved, but I'm not sure what happened

Prettier 2.2.1
Playground link

--parser glimmer

Input:

<Foo class="
"/>

Output:

<Foo class="[object Object]," />
