Text: Spacing between baselines: text selection lost when "+/-" on baseline spacing moves text outside of flowed text frame

Steps to reproduce:

Create a text box (flowed text frame), write a few lines, select all of them & increase baseline spacing until some of the selected text moves outside of the blue box. Reduce baseline spacing and observe weird behaviour

What happened?

Once selected text moves outside of the blue text box, selection is lost and subsequent application of baseline spacing is not applied to all of the previously selected text

What should have happened?

Selection should not be lost, so "+/-" to baseline spacing is fully reversible for the full text that was selected initially
