When undoing files created by the agent it leaves a blank file behind instead of removing it from the 'files changed' list and deleting the file #257566
Description
Type: Bug
Have the agent create a new file due to some instruction, then instruct it to remove it.
The agent may succesfully remove the file but it will still be listed as a file changed.
Hit undo or keep and there will be a blank file instead of unoing the creation or keeping the removal of the file.
This makes it hard to switch to a new conversation as it prompts me to keep or undo the changes. Either let me ignore the propmpt and open a new copilot chat or correctly handle the removal of files generated by the agent, when hitting undo or keep
