<title>CSS Writing Modes test: text-combine-upright with RTL text</title>
<link rel="author" title="Jonathan Kew" href="mailto:jkew@mozilla.com"/>
<link rel="help" href="https://drafts.csswg.org/css-writing-modes-3/#text-combine-upright"/>
<link rel="match" href="text-combine-upright-rtl-001-ref.html"/>
<meta name="assert" content="text-combine-upright renders RTL content in the proper place"/>

<style>
div {
  writing-mode: vertical-rl;
  font: 32px serif;
  margin: 1em;
  padding: .25em;
  border: 1px solid gray;
}
span {
  text-combine-upright: all;
}
#test span {
  unicode-bidi: bidi-override;
  direction: rtl;
}
</style>

Both boxes should render the same:

<div>
<p>foo<span>1</span>bar</p>
<p>foo<span>12</span>bar</p>
<p>foo<span>123</span>bar</p>
<p>foo<span>1234</span>bar</p>
</div>

<div id=test>
<p>foo<span>1</span>bar</p>
<p>foo<span>21</span>bar</p>
<p>foo<span>321</span>bar</p>
<p>foo<span>4321</span>bar</p>
</div>
