Multiple Lines of Text scroll issue when Incident is deactivated

Hello,

on Incident form, we have several fields with datatype Multiple Lines of Text. If Incident is active we can normally write in that fields and if text is longer than field, after click in, there is visible scroll bar like here:

But after we set Incident status at deactivated or done, there is no longer possibility click in the field and scroll. So there is long text and only way, we know, is to show title of field and there is whole text but that is not enough, we want to click in the field and scroll.

Is any way how to make this possible?

Thanks,

Adam
