Link hints open Google's Privacy page in some cases

Describe the bug

On Reddit's feed, when typing f to toggle link hints, <space> to surface an overlapped hint, and [first letter of a two-letter hint], the Google Privacy Policy page is opened instead of the intended link.

To Reproduce

Steps to reproduce the behavior:

1. Go to Reddit's feed
2. Tap f to toggle link hints
3. Look for a two-letter link hint that is overlapped by another hint for a post
   a. If you don't see one, refresh the page or scroll down the feed until you do
   
4. Tap <space> to rotate the stacking order of the link hints
   a. The previously-obscured hint should now be on top
   
5. Tap the first letter of that two-letter hint (a in the example above)
6. See the Google Privacy Policy page being opened instead of the intended link

Browser and Vimium version

• This bug was observed in both Google Chrome and Brave:
  • Google Chrome: v135.0.7049.85 (Official Build) (arm64)
  • Brave: v1.77.97 with Chromium v135.0.7049.84 (Official Build) (arm64)
• macOS: v14.6.1 (Build 23G93)
• Vimium: v2.2.1

What I've tried

• Restarted the browsers and computer
• Reinstalled the Vimium extension
• Confirmed that there is no conflicting Vimium options. What I have:

{
  "keyMappings": "map F LinkHints.activateModeToOpenInNewForegroundTab\nmap w LinkHints.activateModeToOpenInNewTab\nunmap <a-p>\nmap ap togglePinTab\nunmap r\nunmap x\nunmap J\nunmap K",
  "linkHintCharacters": "arstneiofpcluh",
  "scrollStepSize": 70,
  "settingsVersion": "2.2.1",
  "exclusionRules": [
    {
      "passKeys": "",
      "pattern": "https://docs.google.com/*"
    }
  ]
}

Start by reproducing the Reddit feed case in Chrome or Brave using the listed key sequence, including rotating an overlapped two-letter hint with Space. No source file or test is named; done means selecting the first letter of the surfaced hint opens its intended link rather than Google's Privacy Policy page.
