Windchill 13.0 customization - ThingView thumbnails becomes unresponsive

I'm experiencing an issue with a customization i'm implementing. I'm using the PTC.wvs.webgl.insertThumbnailViewerAt(...) method to display multiple 3D models on the same page. At first, everything works as expected - all models render correctly and respond to user interactions (move, rotate, ...). But, after few seconds, the thumbnails start becoming unresponsive to user input one by one, and become like static images. The strange thing is that the issue isn't consistent - the last thumbnail to remain interactive keeps working properly forever, allowing user to rotate, move, and interact with like a 3D thumbnail.

Has anyone else encountered this issue? I'd appreciate any help in troubleshooting and understanding why the thumbnails are becoming unresponsive and explore solutions to prevent this behavior .
