Last lines of text on QTextEdit and QPlainTextEdit are not visible on Split view landscape mode

Preconditions:
Application includes QMainWindow with one QTextEdit or QPlainTextEdit.
Application view is on landscape mode.
QTextEdit or QPlainTextEdit size is higher than the split view area reserved for displaying the text input field.

Test steps:
1. Tap the input field on QTextEdit or QPlainTextEdit
--> split view is opened. As the QTextEdit or QPlainTextEdit size is higher than the split view area reserved for displaying the text input field the lower part of the QTextEdit or QPlainTextEdit is covered by virtual keyboard.
2. Start typing text to many lines.

Expected result:
All text lines on QTextEdit or QPlainTextEdit are visible on split view. Scroll bar is displayed on QTextEdit or QPlainTextEdit when input field includes more text lines than can be displayed on QTextEdit or QPlainTextEdit. User can scroll and see all text lines.

Actual result:
Last text lines on QTextEdit or QPlainTextEdit input area are not visible on split view (when the textEdit includes so many text lines that it does not fit to reserved split view area). QTextEdit or QPlainTextEdit scroll bar comes visible but user cannot scroll the text so that the bottom text lines would be visible on split view.
