Web Inspector: Regression: Showing of color swatches no longer works in Details Sidebar

[Tobias Reiss]

I introduced a regression by trying to fix an ESLint issue. The ESLint report was correct but the fix was wrong.

I think codeMirrorTextMarker.find() can return null/undefined. Maybe this need a null check and early return?

Nit: If that's the case I would rather create a new bug because I just re-enabled the code that was here before I removed it. Just without the variable declaration that initially triggered the ESLint report. I can investigate into the missing null check afterwards, if that's okay for you?

Fair enough.
