windowDidResize was using [window frame] which includes the title bar height (28px on macOS). This caused the webview to be resized to the outer frame dimensions and window.innerHeight to jump by 28px on any resize event. The window is created with initWithContentRect: which correctly uses the content area, but windowDidResize used [window frame] for both the webview resize and the resize handler callback, creating an inconsistency. Fix: use [containerView bounds] for webview resize and contentRectForFrameRect: for the resize handler dimensions. Fixes blackboardsh#215

There was a problem hiding this comment.
I merged in main and resolved the conflict (part of this already got fixed by another PR).
Nice work! thanks! ✨

The window is created with
initWithContentRect:which correctly interprets the size as the content area. However,windowDidResize:used[window frame]for both:[abstractView resize:fullFrame ...]) — making the webview 28px taller than the content areaself.resizeHandler— reporting the outer frame size instead of content sizeFix
