<title>CSSOM test: no side effects from setting "height"</title>

<p>
Historically, the Apple Safari web browser has added an "intrinsic margin" to
form controls which do not specify a `height`. It removed this margin following
modification of the `height`. <a
href="https://bugs.webkit.org/show_bug.cgi?id=107380">This non-standard
behavior was identified as a source of confusion for web developers.</a>
