Virtualbox shared clipboard doesn't work if I copy paste a large string from host to guest.

Through some trial and error I determined it seems to break when I go over 512 characters of string length.

How can I increase this limit? 512 char limit is ridiculously low, most XML/Yaml configuration snippets are larger than that.

Please try to reinstall/update VBox GuestAdditions.
p.s. I faced the same issue after updating VBox 6.1.10 -> 6.1.14. (after update shared clipboard size was limited to 512 chars)
