@HermesSbicego-Laser I'm working on #8773 now and there were some merge conflicts between 1.10.x and dev regarding some of the client-side assets. Recompilation works fine (which I find a positive surprise considering how outdated the compilation pipeline is) with Node v7 in the Task Runner Explorer.

I ran it first just on 1.10.x to validate the output and got the following results:

• 233 js/css files were updated across various modules, but just their sourceMappingURLs.
• In Orchard.Resources, a few files were updated functionality-wise, but everything still seems to be working fine there.
• In Orchard.Layouts, which is affected by this PR, the LayoutEditor style and script are both updated functionality-wise.

Layouts still works great, but the layout editor toolbox became very restricted in terms of its height due to this specific line:

Can you please check what happens if you do a full recompilation of client-side assets with the rebuild task? I've committed the output from my local testing to the issue/8773-1.10.x branch (13bbb43) and then a rework of the sticky behavior (c420676).

@BenedekFarkas Could you please clarify what do you need us to check? What branch do you need us to try and rebuild the assets on?

I've moved on from this for a while, so I recompiled everything and resolved the issues already, but the issue was present on this PR's branch, as well as 1.10.x and dev.
