Bug Description

Using a bq 4.5 on rc-proposed r76, hold a tap on an icon to get the details view, the info are slow to load (like the page is empty for 1O seconds before content start being displayed and internet is not laggy in the browser/other devices) and while the "load-bar-at-the-bottom" is bouncing it's not possible to scroll on the page (either vertically nor horizontally in the images row)

The fact that the view is disabled while contents are loading is a design decision, you'll have to take it up with them if you think it's a bad idea.

About the slowlyness from what i can see we're making the calls to the lower layers as fast as we can and the delay comes because the lower layers take some time in populating the models we get returned with content.

Adding the lower layers for comment.

After investigating it a bit it seems that unity8 is still requesting multiple previews at a time (it was originally implemented that way to have next preview readily available when user swipes between previews, but I thought it was supposed to be disabled?) - I see even 4 preview requests at a time on longpress. Moreover, in the logs it looks like among them there is always a request for the first app from Apps category (Amazon in my case), even though I long-press one of the last app icons in that category. For every preview request clickscope performs two network queries (for package details and for its reviews).

I'll use this bug for "takes too much to load" because as Pawel found out we're using too many previews some of them in the wrong order.

As mentioned if you disagree with blocking the view until the loading is done please file a new bug so we can add ubuntu-ux there

Sounds good to me, thanks. I'm going to wait for those fixes to land and see how things feel then
