Unusual output when rendering to HTML

DavidAntliff commented 6 years ago

I have a simple markdown document:

# Test

It renders like this in both Chrome and Firefox:

Any idea what is causing this? It's only just started happening.

The source HTML looks like this:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>test.md - Grip</title>
  <link rel="icon" href="/__/grip/static/favicon.ico" />

Duplicate of #244. Be sure to upgrade with pip install --upgrade grip. Thanks!

DavidAntliff commented 6 years ago

Ah, sorry, I searched open issues for "aria-hidden" and got no hits, so didn't realise there was a dup.

Upgrade has fixed the issue. Thank you.

No problem! This issue will likely contain words that other people will search for, so thanks for taking the time to open it when you didn't see any results 😃
