justify text with spaces - a bug

Sorry to annoy you.
Here another quirck.

  1. Make a paragraph with justify text
  2. Make show invisibles (Menu: Format/Options) and point the cursor after the last character - just before the invisible “P” reversed.
  3. Make a space.
    Bug 1: the last line is stretched from the left to the right margin even if there are just few words in it. Type a letter and it turns normal.
  4. Remake text justified left only. Make the cursor in the same position of point 2.
  5. Make several spaces.
    Bug 2: the cursor in the screen does not react on the spaces. Type a letter and the several spaces appear.
