Are you experiencing a change in font size when a link is clicked?

I'm not sure if it's a Chrome update that caused this because I can't recall it behaving like this earlier this year. I'm on Version 83.0.4103.116 (Official Build) (64-bit)

Yes! It only started happening a few months ago. And of course the extension hasn't been updated during that time.

It's honestly pretty bizarre. It seems to scale the whole popup somehow and if you inspect element, you see that the popup width and font size values have not changed at all! Further, disabling and re-enabling those values seems to bring everything back to normal.

It's not even the only graphic glitch I've been experiencing in Chrome. These days, if you close tabs too quickly, the favicon or loading circle doesn't get cleared:

I was hoping that these maybe related and that this issue will just go away on its own when the Chrome devs get around to fixing whatever it is they messed up.

Let me know if you have any ideas.

I've been playing around with it and for some reason it looks like it only scales when the href in the links has a subdomain in it. With this in popup.html if I remove www. it doesn't scale but adding it back causes the size increase. Can you confirm you're getting the same?

<style type="text/css" media="all">
  body {
    font-size: 13px !important;
    width: 500px;
  }
</style>

Wow, that does work. But it gets weirder ...

• The glitch happens for www.reddit.com, np.reddit.com, and old.reddit.com, but not for i.redd.it, api.reddit.com, youtube.reddit.com and every other subdomain that I tried
• www.google.com causes the popup to actually shrink instead of expanding
• en.wikipedia.org works fine
• The glitch is not related to any JS code. It occurs even after disabling all event listeners.

I also discovered that editing the href to an invalid URL causes the popup to immediately go to the DNS error page (without any clicking), which means Chrome is doing DNS pre-fetching even though I have pre-loading disabled in the settings.

i.redd.it causes the biggest increase for me. I honestly don't understand what's going on. I was thinking maybe it's the headers sent by Reddit but then how would that end up causing the popup to scale.

I tried this simple extension in Firefox and no link behaves like in Chrome:

manifest.json:

{
  "manifest_version": 2,
  "name": "Test Extension",
  "description": "Tests popup link scaling bug",
  "version": "0.1.0",
  "browser_action": {
    "default_title": "Scaling bug",
    "default_icon": "icon.png",
    "default_popup": "popup.html"
  },
  "icons": {
    "16": "icon.png",
    "48": "icon.png",
    "128": "icon.png"
  },
  "manifest_version": 2,
  "permissions": [
  ]
}

popup.html:

<style type="text/css" media="all">
  body {
    font-size: 13px !important;
    width: 300px;
  }
</style>

Where is this pre-loading setting you mention?

It's in the 'cookies and other site data' section. Just search for "preload".
