Issue description

Lets's say you have a script using documentation comments, it will have it's own Documentation page generated in the editor.

If you close the editor, then open the editor again, work on another, unrelated script and save it, close the editor and open it again, the documentation page for your first script will be gone.

Searching for it will also give no results:

Then to get the documentation generated again, you have to open the first script, make some change to it and save it. The old trick of commenting/uncommenting any line and saving also works.

Steps to reproduce

• Create any documentation comments for any script
• Open its documentation
• Close the project and open again
• Do some change to any other script and save
• Close the project and open again
• The generated documentation for your first script will be gone, and if your search help for it it will have disappeared.
