starting a paragraph with custom component doesn't create <p>

Bug report

I created a custom component in .vuepress/components/LaTeX.vue to typeset the LaTeX logo properly (just a span in HTML with CSS).

If I start a paragraph with that component like this:

<LaTeX> creates beautiful....

then the output is lacking the <p> element around the paragraph.

But if I now change the component's name to .vuepress/components/latex.vue, it works as expected.

Steps to reproduce

Create two custom components in .vuepress/components/LaTeX.vue and .vuepress/components/latex.vue, each with the contents:

<span>LaTeX</span>

and then create a README.md:

<LaTeX/> creates beautiful text.

<latex/> creates beautiful text.

What is expected?

I would expect both paragraphs to be identical.

What is actually happening?

However, the first paragraph is

<span>LaTeX</span> creates beautiful text.

the second one is

<p>
<span>LaTeX</span> creates beautiful text.
</p>
