BbCopyText: Tooltip reappears when switching tabs.

[garrenf]

With the new update, I've discovered that the last BbCopyText on a page to be clicked will have it's tooltip reappear and stick on screen when switching tabs. The only way to hide it is to hover over the text again.

Fixed in #512, merged to develop for the next release.

Returning to a background tab makes the browser restore focus to whatever held it. That fired focus on the <span role="button" tabindex="0">, which showed the tooltip — and nothing dismissed it, because no mouseleave ever followed a pointer that had never been there.

Your read on "with the new update" is right, and worth recording. The focus path was always wrong; until 3.16.0 the tooltip was a transparent copy sitting in the layout. Moving it through the floating portal means it is mounted only when open, so the same mistaken open turned from an invisible tooltip into a visible one.

It now opens on focus only when a Tab keydown landed just before it — the same helper that fixed #504. Hover and keyboard Tab both still open it; a programmatic focus no longer does. Verified all three in a real browser.

Thanks for the video, it made the trigger obvious.
