Why is there no cursor when magnifier is enabled?

Sep 29, 2012
In System Settings > Language & input one can enable /disable the magnifier.

But this setting does more than the title implies: when magnifier is enabled, there is no draggable cursor to show the current position in a piece of input text. That is only there if the magnifier is disabled.

Also, the option to select all text in a textbox is available only when magnifier is enabled.

So is there a specific reason for this apparent discrepancies?
