Drag and Drop functionality doesnt work on Linux

[grofit]

I am not entirely sure if this is the correct place to raise the issue but happy to move it to one of the other repos if needed.

So I have a Blazor Photino app which I have been using in windows for a while and it all works fine, however I am now trying to get it working in Linux (and OSX) and so far everything seems to be working ok with v4.x, however I have just noticed that drag and drop functionality doesnt seem to be working.

A quick look seems to indicate that certain flags may need setting (and I appreciate this may only apply to certain distros):

I am currently testing with:

• Ubuntu 24.10
• .Net 9
• Blazor Photino v4.0.13

There is a linux dev build available for testing as an artifact on our repo here:

On windows you drag and drop elements from the right into the flows, but on linux it doesnt seem to register the drops, let me know if you need any more information.
