Enter key causes TextEdit to add a space instead of going to the new line

[cppdev123]

When using TextEdit and pressing enter a space is added then when you try to write the text goes to the new line. Instead a new line should be added when pressing Enter

Thanks for the bug report!
I can reproduce the problem in the gallery on wasm in the browser (firefox). But it works fine on the native linux with both backend.

(So this is most likely a bug in wasm_input_helper.rs)

Actually no, i can also reproduce on desktop with the GL backend. So this is not a wasm problem.
The problem only happens if we are at the last position of the TextEdit. The Qt backend seems to work.

I think this is related to the position of the cursor.
We have some special logic when the cursor is at the end of the text:

slint/internal/backends/gl/glrenderer.rs

Lines 400 to 401 in a2484cf

	&& (range.contains(&cursor_pos)
	|| (cursor_pos == range.end && cursor_pos == text.len()))

But that kind of fails if the last character is a \n
Because the \n is at the end of the line, and there is no more line after that (the empty line is not rendered) then we can't know the position of the cursor in the next line in that loop. We would need to special case it.

Another problem is that the selection is drawn over the whitespace at the end of the lines, which the Qt backend doesn't do
