Find mode not working within HTML <code> blocks that separate spaces with <span>s

Bug Description

Entering find mode via /, I am unable to match text with spaces in HTML code blocks. Looking into the code, the HTML doesn't actually connect the text (typically for styling reasons like so):

<span class="line">
  <span style="color: var(--color-pink-400)">npm</span><span style="color: var(--color-sky-300)"> install</span>
  <span style="color: var(--color-sky-300)"> tailwindcss</span>
  <span style="color: var(--color-sky-300)"> @tailwindcss/vite</span>
</span>

To Reproduce

Steps to reproduce the behavior:

1. Go to https://tailwindcss.com/docs/installation/using-vite
2. Type / to "Enter find mode"
3. Type npm install to try to find the text npm install tailwindcss @tailwindcss/vite

Browser and Vimium version

Vimium Version: 2.1.2

Notes

I've tested with "Treat find queries as JavaScript regular expressions" set to true and false, still doesn't work. I'm wondering if there's some regex I can remember to include that matches spans, but am thinking it's probably something more complex considering the spans split up the text.

Reproduce the issue on the Tailwind CSS installation page by entering find mode with / and searching for npm install. Start at Vimium’s find-mode entry point and trace how text is read across HTML code-block spans. Done means a normal find query can match text separated by nested <span> elements, with regex mode both enabled and disabled.
