gitiles fails to render HTML tables in Markdown content

[bcmills]

Steps to reproduce

1. Open https://go-review.googlesource.com/c/website/+/324489/1/_content/ref/mod.md#2824.
2. Click the gitiles link in the diff header.
3. Scroll to the section containing the new table.

Expected

Since HTML tables are not, to my knowledge, a grave security risk, the HTML table in the document should be rendered — in much the same way that GitHub renders the table below.

Name	Command	GOVCS default	Secure schemes
Bazaar	bzr	Private only	https, bzr+ssh
Fossil	fossil	Private only	https
Git	git	Public and private	https, git+ssh, ssh
Mercurial	hg	Public and private	https, ssh
Subversion	svn	Private only	https, svn+ssh

Observed

The table is dropped from the rendered document, without even any visual indication that content has been omitted.

I think gitiles can't support html tag. I tried to <table>, <script>.

Finally i used markdown table.
