[HTML] Highlighted inline code within strikeout is not applied correctly

[mpark]

Consider: ~~foo `constexpr`{.cpp} bar~~
With pandoc foo.md --output foo.html --self-contained this currently generates:

The desired output would be something like:

---

This seems to be caused by the display: inline-block from

skylighting/skylighting-core/src/Skylighting/Format/HTML.hs

Line 170 in 8c650b6

"code.sourceCode > span { display: inline-block; line-height: 1.25; }"

.
Changing this to display: inline produces the desired output.

@dbaynard may be able to say more than I can about why display: block is in there...

This is a bug, introduced in 0b07bbc when the line span tags were simplified — I didn't notice the clash.

<code class="sourceCode cpp"><span class="kw">constexpr</span></code>

This is treating the span as a line. The css should probably restrict that behaviour to pre > code.sourceCode > span. I'm making the PR, now
