Clipboard (get) not working in RDP connections when copying +54 characters
Describe the bug RDP clipboard (get) is not working if the clipboard on the remote PC contains more than 54 characters. This happens both in RDP Connect (via Desktop) and in Web RDP. Auto Clipboard or not doesn't make a difference. This is not a browser issue. Tested on multiple computers, multiple instances.
To Reproduce Connect with RDP to a remote computer. HOST -> REMOTE (Clipboard SET) always works. REMOTE -> HOST (Clipboard GET) only works for =< 54 characters.
Expected behavior Clipboard GET should copy > 55 characters too.

Notes: I've narrowed down the issue to here https://github.com/Ylianst/MeshCentral/blob/master/rdp/protocol/pdu/cliprdr.js#L73-L104 It seems when it does the clipPDU, the offset is 11 instead of 10? And it seems like the data that get received has an extra byte? I just can't work out why or where?
