Describe the bug When exporting a drawing and embedding it into Notion, the Toolbar is missing in the Notion preview (see the first screenshot). However when clicking on "View original" in context menu in notion - it opens the view in a browser window where the toolbar is displayed as expected. Sometimes (but not always) when exporting multiple pages - the toolbar is displayed as expected (see the second screenshot). I could not find the exact pattern here, but in general it looks like if some of my pages contain copy-pasted content from my older drawings - then the multi-page export is most likely to have the toolbar. Also the toolbar is displayed as expected in those my drawings which I exported and embedded around 6 months ago. So it looks like it's happening only for recently created/embedded drawings. This bug prevents me from arranging the imported view to fit the resized Embed-box.

To Reproduce Steps to reproduce the behavior:

1. Create a drawing in Draw.io desktop app (macOS)
2. Click in menu > Export as > Embed > Notion
3. Click "Create" and then "Copy"
4. Open Notion
5. Add an Embed block
6. Paste the copied URL
7. Hover the block - no toolbar is displayed (see the first screenshot)

Expected behavior The toolbox is displayed on hover in Notion.
