Hovered element is sometimes incorrect

[Lemonymous]

Possible files:

mod_loader\ui\root.lua, mod_loader\ui\base.lua, mod_loader\modUi\dialog_helper.lua

Description:

When ui elements are created, and a click event is immediately followed, the wrong element can be hovered, and in turn be clicked.

How to reproduce:

A: Error when dismissing background panes created by dialog_helper.lua:

1. Create two background panes. For example by opening [Mod Content] > [Configure Mods]
2. Click twice rapidly outside the window to dismiss both panes quickly. If done quick enough, the game will crash with an error.

B: Clicking a button hidden by a background pane:

1. Open a window with a background pane that hides other buttons. For example [Mod Content] > [Arrange Pilots]
2. In quick succession, repeatedly click the button [Configure Mods]. If done quick enough, you will keep clicking the button hidden by the background pane, and keep opening the same dialog again and again.
3. When closing the menu, many clicks will be needed to get back to the main menu from all the dialogs you have to dismiss.
