ChatGPTEditwithInstructions strange behavior

Hi,
First of all thanks for this plugin that only begins to change the way I write code 🙏

I'm getting to use edit with instruction more and more and I encountered a strange behavior: sometime the code displayed on the left is not my full code. Sometimes it's a good thing, sometimes les... Is this a bug or a feature ? If the second, is there a way to select which code to use ?
Thanks

Start by reproducing the behavior with ChatGPT's edit-with-instruction feature and trace how the code shown on the left is selected. The issue does not name a file, entry point, or test, so first identify the relevant implementation and existing coverage. Done means determining whether the partial code display is intentional and, if it is a bug, making the displayed code consistent or selectable.
