This was causing hover_at(editor, None) to be called, which would hide any active hovers. The fix is simple: don't call hover_at when we're over an inlay position. The inlay hover is already handled by update_hovered_link, so we don't need to do anything else. --- crates/editor/src/editor.rs | 97 +--------- crates/editor/src/hover_links.rs | 251 +++++++++++-------------- crates/editor/src/hover_popover.rs | 253 +------------------------- crates/editor/src/inlay_hint_cache.rs | 85 ++++----- crates/project/src/lsp_store.rs | 161 +--------------- 5 files changed, 141 insertions(+), 706 deletions(-) diff --git a/crates/editor/src/editor.rs b/crates/editor/src/editor.rs index 91a1a1d86a..69b9158c31 100644 --- a/crates/editor/src/editor.rs +++ b/crates/editor/src/editor.rs @@ -1061,11 +1061,10 @@ pub struct Editor { read_only: bool, leader_id: Option, remote_id: Option, - hover_state: HoverState, + pub hover_state: HoverState, pending_mouse_down: Option>>>, gutter_hovered: bool, hovered_link_state: Option, - resolved_inlay_hints_pending_hover: HashSet, edit_prediction_provider: Option, code_action_providers: Vec>, active_inline_completion: Option, @@ -2080,7 +2079,6 @@ impl Editor { hover_state: HoverState::default(), pending_mouse_down: None, hovered_link_state: None, - resolved_inlay_hints_pending_hover: HashSet::default(), edit_prediction_provider: None, active_inline_completion: None, stale_inline_completion_in_menu: None, @@ -20354,99 +20352,6 @@ impl Editor { &self.inlay_hint_cache } - pub fn check_resolved_inlay_hint_hover( - &mut self, - inlay_id: InlayId, - excerpt_id: ExcerptId, - window: &mut Window, - cx: &mut Context, - ) -> bool { - if !self.resolved_inlay_hints_pending_hover.remove(&inlay_id) { - return false;
