I was going to post separatedely, but these bugs are very related so it feels like a combo:
Normally when opening the context menu of your own extension, and clicking on “Edit”, it will open the editor to modify the extension.
But when clicking “Edit” on extensions that are not yours (the official Gdevelop ones), it will open the extension overview (the description and stuff) and then you will have to click on the button “Open in editor”.
If people wanted to see the extension overview they would just click on the extension, they would not do the extra steps of opening the context menu and clicking on “Edit”.
Even after modifying the description of official Gdevelop extensions at the editor, it will still display the default one when you open the extension overview, that difficult the things for whoever is updating an extension.
