As mentioned on the PR, the proper use of the HandleTab from Skins module of ElvUI is to send the parent tab into the function, which will then skin its children
But right now the .selected element of the tab is being sent instead, this causes other addons and plugins to throw errors because the .selected element is not the actual tab and lacks the OnClick function, if you swap to HandleTab(tab) the error will stop and the tab will be properly skinned by ElvUI
