This is a feature, not a bug. The sizes of icons with and without previews are independently configurable in Settings > View Modes. However I'm not sure how useful it really is. I don't know the history behind why icons with previews shown historically had their own size different from icons without previews shown, but I'm not sure it really makes sense. My inclination is to remove the feature. Does feel otherwise or know the history here?
Well, I really want my images larger than my icons, so whenever I click the Preview toolbutton, it should automatically switch to the larger size.
I don't know the history behind this feature. When I wrote this report I wasn't sure if the current behavior is a bug or intentional. I have wrote this report anyway because at first the current behavior doesn't make sense to me and I can't think on any situation in which different icons sizes depending on the state of preview feature could be useful.
Dolphin's icon view only supports a grid layout with a fixed item size. Of course you could keep icons at their configured size in preview mode, and only enlarge previews, but then users would probably complain about the larger gaps between the icons. The actual fix would be a dynamic layout system, allowing items of different sizes (see e.g. Google's Picasa). That is not an easy task, and I don't know any Qt based item view that does this.
I don't understand the problem, or the use case for wanting icons with previews to be larger when icons without them, or the use case for turning previes on or off periodically, or even for the matter why you would not always want to have previews turned on.

Sometimes I disable the previews before taking a screenshot or recording my screen for privacy reasons.
Apparently this behavior causes bug 288118.
