On-device runs exposed three bugs the e2e suite could not (it never feeds layout feedback, and runs headless without size events): 1. WrapIndex poisoning from zero-width shapes. The first frames are built before the window size is known (px=0x0); the renderer shapes the editor window at zero width, where every line wraps into many visual lines. When that feedback arrives, applyWrapCounts writes the inflated counts to the window's lines. Normally the app stays on those lines and re-shapes them at a real width, which corrects the counts before anyone notices. A restored scroll moves the viewport away instead, so the poisoned counts persist and map the restored scroll offset to the wrong line (2000 landed on line 11 of 200). The frame now carries ViewportDegenerate (set at frame-build time, since feedback delivery lags shaping by a frame), and the main loop drops layout feedback for such frames. 2. Session saving suppressed forever after a successful restore. saveSessionIfChanged suppresses saves while l.session is set, and only abortRestore cleared it — the success path never did, so an app restored from a session never persisted new state. The snapshot has fully landed once the cursor/selection/find have landed with the content and the armed scroll has landed (or there was none); clear l.session at both points. 3. gofmt on restore_test.go (comment alignment). |
