[Bug]: Export icon tooltips in SQL Notebook results are delayed and inconsistent

[croblesm]

Description

Tooltips on the new export icons (CSV, Excel, JSON) behave inconsistently in the SQL Notebook result grid:

• On first hover, the tooltip takes an unusually long time to appear, well beyond the standard VS Code tooltip delay.
• Once shown, the tooltip sometimes disappears on its own before the cursor moves.
• Moving directly from one export icon to another often produces no tooltip at all on the second icon.

tooltips appear after the normal hover delay, remain visible while the cursor stays on the icon, and show consistently when moving between adjacent icons.

First hover — tooltip eventually appears after a long delay:

Tooltip disappears, or fails to appear when moving to a different icon:

Steps to Reproduce

1. Open a SQL Notebook and run any query that returns rows (for example SELECT * FROM dbo.authors;).
2. Hover over the CSV export icon above the result grid and wait for the tooltip.
3. Without leaving the toolbar, move the cursor to the Excel icon, then to the JSON icon.
4. Repeat with short pauses on each icon.

I wasn't able to repro this tooltip issue. This is the behavior that I'm seeing with the tooltips with SQL Notebooks.
