Bug: Lag / Stack Overflow on Phoenix Search Result

**Describe the bug**
Stack overflow on long search result.

**To Reproduce**
Steps to reproduce the behavior:

1. Add Phoenix as a source.
2. Search for `testing-librar` (problem occurs when typing the second `r`)

Result:

Page lags for a while, then an error shows in the console. I can continue to interact with the page, but every action takes several seconds, until I delete the search term and the page becomes responsive again.

It freezes every time I search with `testing-librar` but does not reliably freeze when finding the same search result by searching for other terms.

**Expected behavior**
No lagging, text in search results is trimmed.
A clear and concise description of what you expected to happen.

**Screenshots**

**Desktop (please complete the following information):**
- OS: macOS Big Sur
- Browser: Firefox 95.0.1

**Additional context**
I recently started trying DevDocs for the first time. I added a few sources, and tried searching for a few terms, but it's otherwise a fresh state.

Reproduce the issue by adding Phoenix as a source and searching for `testing-librar`, especially when typing the second `r`, while checking the browser console for the stack overflow. Done means the search remains responsive and long result text is trimmed without the reported error.
