Asset Browser/Inspector: Assets should only open in the Inspector after the click is released, rather than when pressed

[DragoniteSpam]

Is your feature request related to a problem?

This has been an annoyance for a while in places like the room editor but now that CE2 is designed around the use of inspector windows full-stop, it's become even more of a problem.

A number of properties in GameMaker (object sprite indices, asset variable definitions, things in the room editor, etc) allow having an asset assigned to them by clicking and dragging something from the Asset Browser. This is a big time-saver over clicking on the menu and searching for the asset yourself, but it doesn't work in inspectors because as soon as you click on an asset, it opens in the inspector instead.

You can get around this by locking the inspector, but locking the inspector every time you want to assign something and unlocking it when you're done is really annoying.

Live footage of me trying to assign a sprite to an object:

The most common way for UI to deal with this kind of thing is to only open something for selection after the left mouse button has been released (or to double-click to open, the way we did in workspaces). For example, this is how it works in Unity:

Additional context

This also happens all over the place in the room editor inspector

Yes please, I had been thinking about requesting exactly this. If it doesn't change until the mouse is released, then the dragging to assign workflow works a lot better.

Asset browser now inspects on mouse release, when node was not dragged

We should verify that this fixes 5846 also, as well as 5507.
