Steps to reproduce:
put a self-closed format tag (i.e. <b/> or <i/>) in front of text and it still applies to the block. This was output from an xslt/xml -> html process (no text in the tag, so xsl simplified it to a self-closed tag).
Actual results:
example: <b/>this is a test
is bolded
example: <b></b>this is a test
is not bolded
Expected results:
Because it's a self-closed tag, I expected it to not apply formatting. I realize the HTML standard is loose on open/close of formatting tags, but because it is a closed tag I wouldn't expect it to be applied.

I don't think you can self-close those tags in HTML.
This is an HTML parser thing, but it is interoperable across browsers so I'm pretty sure it is invalid.
Not a bug, see: https://html.spec.whatwg.org/multipage/syntax.html#start-tags:
"Then, if the element is one of the void elements, or if the element is a foreign element, then there may be a single U+002F SOLIDUS character (/). This character has no effect on void elements, but on foreign elements it marks the start tag as self-closing."
In HTML, the LINK and META tags, for example, are self-closing.
These are considered VOID elements, so the self-closing slash is ignored.
Although in both the 3.2 and 5.3 W3C HTML Standard documents deem for text format tags, both open & close tags are not omissible.
An exception case is if an unclosed format tag is within a table, it doesn't continue outside the cell.
