Since [1] when selecting item images, the 'Blocks' tab is displayed while the options are refreshed. This is visible because the image selection awaits an RPC which therefore allows the browser to render the 'Blocks' tab selected version of the display. This commit prevents the return to the 'Blocks' tab to be rendered by waiting for the image info to be obtained on start. Steps to reproduce: - Drop an "Items" block. - Click on an image. - Click on another image. => The options panel flickers on the 'Blocks' tab before showing the second image's options.
