expression coding hint is blocking the cursor line

[Jeroen-GroeneBij]

What is the bug or the crash?

Often, when typing an expression in the expression builder, there is a coding hint popping up, suggesting the next part of the expression. However, also often this is actually blocking the line where the cursor is, so you can't see what your typing.

It would be nice if this coding hint is moved to somewhere where it doesn't block the cursor. For instance, the autocomplete suggestions are always below the cursor.

Steps to reproduce the issue

Open the expression builder, and start building an expression which uses multiple elements, such as concatenate. Start writing the expression, and type , after the first element. This will trigger the coding hint. It will not always block the cursor line, or sometimes block it partially, but at times it will block the cursor line. This behaviour might be dependent on screen sizes, resolutions, or interface settings.

Therefore I think it would be great to move the coding hint to somewhere were it will for sure not block the cursor line.

The issue also occurs using the Python console
