[Balloon Mode] Balloon position misplaced after long text selection + runtime errors on setContents (replaceChild / _iframeAutoHeight) #1585
Description
Version
SunEditor: 2.47.7
Mode: balloon
Wrapper: suneditor-react
When the editor content is long and scrollable, if the user drag-selects text from the visible area toward the bottom (so that the page scrolls during the drag), the balloon UI (or editor’s floating UI) appears anchored near the very bottom (off-screen / non-visible area) rather than near the actual selection/caret. It looks like the selection-change or scroll event updates the balloon’s position using stale layout/scroll coordinates.
And there's one more question
I am experiencing two recurring runtime errors when using SunEditor in balloon mode, especially when calling setContents() (for example, when switching between memos or updating content after API calls).
Errors
Uncaught TypeError: Cannot read properties of null (reading 'replaceChild')
Uncaught TypeError: this._iframeAutoHeight is not a function
