I believe this is a bug.
I have been migrating an application from 4.2 to 5.1.4 and ran into a little issue. The hep text for a page in the original application is about 7702 characters long. But when I try and copy this to the new application in 5.1, it cuts the text off at about 3900 characters.
We need to use the help text which was not limited before. I believe the limit was introduced in the newer version but it should not be extended to help text. Many help texts we have are well over that size.
I asked if anyone knows how to fix this with no response so I am thinking there is no fix. So it must be a bug.
Where can I report this kind of bug (or does anyone know how to fix this?)
