Actual behavior

Hover tooltip extent spans entire extent of paragraph past the location that contains a bibtex citation.

Expected behavior

Expect the tool tip hover to only appear when hovering over the actual citation not over the entire paragraph. The expected behaviour works for issues/problems identified by positron (identified with blue squiggle) where the issue tooltip/hover appears when you mouse over the issue but not for the entire paragraph.

Your environment

R 4.4.2
Quarto 1.8.25
Ubuntu Release: 24.04

Start by reproducing the hover behavior with quarto-file.qmd and references.bib, using the long paragraph and @Smith2020 citation described in the issue. Trace the citation hover handling and compare its extent with the Positron issue hover behavior. Done means the tooltip appears only over the actual citation rather than the surrounding paragraph.
