"End" key doesn't move cursor to the end of the current line for multi-line text

Two reports from the forums about the unexpected behavior of pressing the "End" key on a muti-line text.

Pressing the "End" will move the cursor to the end of the current line.

The cursor moved to the beginning of the next line when pressing the "End" key. This is only happening when the text wraps in a few lines.

Add a multi-line paragraph in the app
Move the cursor to the beginning of the paragraph
Press the "End" key on your keyboard
Notice the cursor moves to the beginning of the next line instead of the end of the current line
