Stored Range Selection Offsets Not Updating After Editor Content Changes

[manufac-kbhatia]

Hi Lexical Community,

I am developing a custom plugin for my editor, built on top of Lexical, where I need to store the ranges of text selections made in the editor. My goal is to be able to access the startOffset and endOffset of each stored RangeSelections at any given time. However, when changes occur in the editor, and I try to retrieve the updated startOffset and endOffset for the stored RangeSelections, these values are not updating as expected.

In a typical JavaScript environment (vanilla JS), when I use getSelection to capture selection ranges and store them in an array, these stored ranges act as memory references. As the document content changes, the browser automatically updates these references, allowing me to consistently retrieve the updated startOffset and endOffset for each range.

However, when trying to achieve the same behavior with Lexical’s getSelection (rangeSelection), the stored RangeSelection doesn’t automatically update when the editor’s content changes. It seems Lexical is not updating the RangeSelection in the same way that the native getSelection in the browser does.
