Cloning Scripts via PluginMouse.KeyDown and parenting it to Workspace without delay causes studio to freeze.

This is the most obscure bug I’ve ever seen, but here is a repro:
http://pastebin.com/7dgSsd84
Save this as a .lua file in Appdata/[…]/Roblox/Plugins. Press “c” to create a LocalScript and clone it.

Doing some tests, I’ve seen it only happen when run through PluginMouse.KeyDown, and only for Scripts, LocalScripts, and ModuleScripts.

if you wait one second between using Clone() on the object, and parenting it to Workspace, it does not freeze.

I’m using Windows 10.

I have gotten a PM confirming this isn’t just me.

Roblox Studio seems to also be freezing whenever setting the parent of a script (or object containing a script) to nil through a PluginMouse KeyDown event.
