<div id="issue"><b>Broken tiled screenshot scrolling logic</b></div>
<div id="fix">
The tiled screenshot logic was modified to remove window scrolling and
dynamic element positioning, which breaks the capture of dashboard tiles
outside the initial viewport. This change prevents proper screenshotting of
large dashboards that require scrolling to access all content. The original
implementation scrolled to each tile position, waited for settling, and
calculated clip coordinates based on the element's current viewport position.
Reverting to include scrolling and position recalculation ensures correct
functionality.
