Mistake in JavaScript page description

Not really sure where to report this? But I happened to notice that https://plotly.com/javascript/ has an error in the meta description tags.

<meta name="description" content=A free open source interactive javascript graphing library. Plotly.js is built on d3.js and webgl and supports over 20 types of interactive charts.>
<meta property="og:description" content=A free open source interactive javascript graphing library. Plotly.js is built on d3.js and webgl and supports over 20 types of interactive charts./>
<meta name="twitter:description" content=A free open source interactive javascript graphing library. Plotly.js is built on d3.js and webgl and supports over 20 types of interactive charts./>

These 3 tags have no quotes around the content, so it actually resolves to the following, leading to embeds showing the description as "A."

<meta name="description" content="A" free="" open="" source="" interactive="" javascript="" graphing="" library.="" plotly.js="" is="" built="" on="" d3.js="" and="" webgl="" supports="" over="" 20="" types="" of="" charts.="">

I'm not exactly sure what went wrong or if it's present on other pages, but I figured I might as well let you know.

Inspect the page source for https://plotly.com/javascript/ and locate the description, og:description, and twitter:description meta tags. Correct the malformed content attributes, then verify that the rendered tags contain the full description and that embeds no longer show only “A.”
