when tree parent is groupbox almost all of its events are not working
`local ui = require "ui"
local win = ui.Window("tree test","fixed", 320, 600)
local tree = ui.Tree(win,{"sda"})
local gbox = ui.Groupbox(win,"GroupBox",5,300)
local tree_gbox = ui.Tree(gbox,{"sda2"})
function tree:onContext(item)
print("test")
if item ~= nil then
print(item.text)
end
end
function tree_gbox:onContext(item)
print("test2")
if item ~= nil then
print(item.text)
end
end
ui.run(win)`
