Two fixes, both about pages that keep their content inside a panel with its
own scrollbar rather than in the page itself. Dashboards, trading terminals
and admin consoles are usually built that way.

Panels are now captured in full. Content below a panel's own fold used to be
missing from the image, because the capture followed the page while the
content sat inside something else. Both Full page and Select region now
reach it.

No black band beside or below a panel. The column next to a panel is filled
with a colour sampled from the page, and on some layouts that sample came
back black. A region taller than its own content could also end in a black
strip. Both are fixed.

Checked by hand on Google Search Console, Bing Webmaster Tools, Supabase,
Gmail, Outlook and Sensibull.

This is a large update for Firefox. The add-on moves from 0.8.3 to 0.8.45, so several months of work arrive together.

FULL PAGE CAPTURE

• Dashboards now keep their own header and side navigation, instead of returning the content panel on its own. Checked by hand on Search Console, Bing Webmaster Tools, Supabase, Gmail and Outlook.
• Sticky side panels no longer repeat down a long capture.
• Repeating navigation bars are fixed.
• A page with more than two independently scrolling panels is now refused before the capture starts, and nothing is saved, rather than returning an image that looks right and is not.
• A stalled capture no longer leaves the page stuck behind an overlay. It clears itself and says what happened.

REGION CAPTURE

• Selecting a region now scrolls the correct panel on a dashboard.

THE CAPTURE CARD

• Simpler layout, and a help menu: how to use, what's new, report a problem, send feedback, and the keyboard shortcuts.
• Failure messages now stay until you close them, and each one says plainly that nothing was saved and which mode to try instead.

Nothing about how captures are handled has changed. They are taken and stitched on your device, and no image data leaves the browser.
