As reported in rP18933:

The ResetCursor call is done after LoadPage and LoadPage calls the JS init function of the loading screen which calls Engine.SetCursor("cursor-wait").
So this call broke the cursor during loading screen (by resetting after loading and running the JS script files and calling the JS init function) (or any page setting a cursor on int).
Instead, the cursor should be Reset just prior to the page construction.

Also notice that the cursor is not reset when the page is hotloaded.
This is incorrect, since the by design the page is enabled to expect / rely on the default cursor being set when the page is opened (and hotloading is the same as opening the same page again).
Therefore the ResetCursor should actually be in LoadPage.

Reproduce that the statement is necessary and placed correctly by:

1. setting the ingame cursor to the gather cursor by hovering a tree, then open the JS console with F9 and type endGame();. The cursor will be carried throughout the mainmenu despite the session / g_Game having been closed and deleted unless the line is in this place.

2. See the input.js TODO in https://trac.wildfiregames.com/ticket/539#comment:40 and that this is orthogonal to the code in question and not affected.

3. Test that the cursor in the loading screen is the hourglass icon, with and without hotloading.
