Research direction

Start by reproducing the lag through the image editor's rotate action on Windows with a Chromium-based browser, then compare the behavior with upstream filerobot-image-editor issue 306. No repository file or test is named; the work is complete when rotation is fluent or the upstream cause and required integration change are clearly identified.
