Describe the Bug

When reader line spacing is set to 70%, multi-line text clippings/highlights fail to render continuously across lines.

Instead of wrapping cleanly around the selected passage, the highlight box breaks into individual line segments that shift upward and overlay the preceding lines of text, resulting in misaligned, overlapping highlight blocks on tight line-spacing layouts.

Steps to Reproduce

1. Open a book in reader mode.
2. Go to reader typography settings and set Line Spacing to 70%.
3. Highlight/clip a passage of text that spans across two or more lines.
4. Save the clipping and observe the highlight overlay on the reader page.
5. Notice that each line's highlight background is vertically misaligned and overlaps the line preceding it.

Expected Behavior

Clipping highlights should scale dynamically with line-height settings, aligning precisely behind each corresponding line of text without shifting upward or overlapping adjacent text lines.
