Input:

  <div class="container">
    <HomeH />
    <HomeA />
    <HomeX />
    <HomeY />
  </div>

Output:

<div class="container"><HomeH /> <HomeA /> <HomeX /> <HomeY /></div>

Expected behavior:
I am not sure if this was intended, but I was expecting the formatting to keep the original input rather than putting them all in a single line.
