[BUG] <hr> tag doesn't work as intended when style="width: 20%;" is applied

[AlbaneseRemy]

Describe the bug:

The < hr > tag (without spaces) doesn't display correctly when style is applied to it. Without width, it shows entirely

HTML to reproduce the issue:

          <div>
            <p>
              Lorem ipsum dolor sit amet
              <hr>
              Lorem ipsum dolor sit amet
              <hr style="width: 20%;">
              Lorem ipsum dolor sit amet
            </p>
          </div>

Html widget configuration:

    return Padding(
      padding: const EdgeInsets.all(5),
      child: SingleChildScrollView(
        child: Html(
          data: """
          <div>
            <p>
              Lorem ipsum dolor sit amet
              <hr>
              Lorem ipsum dolor sit amet
              <hr style="width: 20%;">
              Lorem ipsum dolor sit amet
            </p>
          </div>
          """,
          onLinkTap: (url, _, __) => LinkUtils.openLink(
            context: context,
            closeWhenOpeningLink: data.closeWhenOpeningLink,
            tour: data.tour,
            url: url,
          ),
        ),
      ),
    );

Expected behavior:
The < hr > tag should only display on 20% of the screen's width
