I'd name this updatePreviewActionState to keep the terminology somewhat consistent (otherwise the code is a bit hard to follow, at least I felt this way when reviewing the patch).

Could you explain why you need to change showPreviewsEnabledBeforeZoom here? As far as I can see this variable just caches the config value, and thus should only be set in _k_toggleInlinePreviews?

Without this the previews are always disabled when opening the dialog. This was added to enable it and then disable it right after if the read config was disabled in the k_toggleInlinePreviews function.

(Or just use @ngraham's wording instead of inventing your own, because as a native speaker he often gets it quite right: "Previews are automatically disabled for icons smaller than {threshold]", or simply "Previews are automatically disabled for small icon sizes.".)
