Describe the bug
Shape data is inserted as text to the previous inserted shape.

To Reproduce
Steps to reproduce the behavior:

1. Start a new Drawing in the Windows Desktop App
2. Insert a shape, e.g. a circle
3. Copy the Circle using Ctrl + C
4. Press Ctrl +V twice without any interaction inbetween. On the second Ctrl + V the (SVG?) encoded shape is inserted as text to the previous

Screenshots

draw.io version (In the Help->About menu of the draw.io editor):

• draw.io version v29.6.6

Desktop (please complete the following information):

• OS: Windows 10

Additional context
The resulting drawio-File is attached here. I'm not ablte to trigger this behaviour after clicking anywhere, even when I click on the inserted element and the selection does not change.

The bug does not occur when using Edit -> Paste, also pressing Ctrl + V after using Edit->Paste will not trigger this bug.
The bug does not occur in the online version (tested in Firefox, Chrome, Edge).

Summary: When a shape is copied and Ctrl+V is pressed twice in rapid succession in the draw.io Desktop App on Windows, the second paste inserts the shape's encoded data (SVG/XML) as text into the previously pasted shape instead of pasting a second copy of the shape.

📝 Additional Information Needed

To help us investigate this more effectively, could you please provide:

• Does this issue also occur when using Edit -> Paste from the menu instead of Ctrl+V?
• Does the issue reproduce if you add a small delay (e.g., 1 second) between the two Ctrl+V presses, or does it only happen with rapid successive presses?
• Have you tested whether this also happens in the web version of draw.io (app.diagrams.net) to help isolate whether it's a desktop-specific clipboard handling issue?
