Actually, This only happens when I do a `setq-default`
Setting it only for a single buffer with a `setq-local` seems to not cause the problem described above

Mouse clicks on some text in an emacs window does not correctly position
the point when the line-height is set to some value and the text is
scaled to become larger

Steps to reproduce with emacs -Q
- Open a new buffer (C-x b *test-buffer RET)
- Yank few lines of text from somewhere
- Eval (M-:) the following:
  `(setq-default default-text-properties '(line-height 1.1))`
- Scale text to make it larger (C-x C-= = = =)
- Click on any line to place the point at that location.
- Point is placed few lines further below the click position

- Reset the line-height to nil by evaluating:
  `(setq-default default-text-properties '(line-height nil))`
- Click on any line to place point at that location.
- Point is placed correctly
