Can not scroll to target row for long table. [bug]

[daiwhea]

What happend?

I want to display a long [up to 5000+rows] and complicated [more than 10+ columns] table, and jump to a target row. But the table content is not fixed, it is computed by some condition. And after it was computed and displayed, it should jump to that target row.

I have tried the code from here: #397 (comment)

It does work for existed and simple table. But if I increased rows up to 5000 and create table content dynamically, it won't jump to that row. And if you move mouse, it will jump after mouse moving. I think this may because I haven't ask giu Update correctly, but it won't work with g.Update() called.

Code example

main.go

// put your code here!

package main

import (
	g "github.com/AllenDang/giu"
	"github.com/AllenDang/imgui-go"
)

var (
	scrollTrigger bool
	scrollIndex   int
	lines         []*g.TableRowWidget
)

func loop() {
	g.SingleWindow().Layout(
		g.Button("Scroll to row 448").OnClick(func() {
			createLines(5000)
			scrollTrigger = true
			scrollIndex = 448
			// g.Update() // add this line doesn't work as wanted
		}),
		g.Table().Columns(g.TableColumn("Col1"), g.TableColumn("a"), g.TableColumn("b"), g.TableColumn("c"), g.TableColumn("d"), g.TableColumn("e"), g.TableColumn("f"), g.TableColumn("g"), g.TableColumn("h"), g.TableColumn("i")).Rows(lines...),
	)
}

func main() {
	wnd := g.NewMasterWindow("Hello world", 600, 200, 0)
	wnd.Run(loop)
}

func createLines(total int) {
	for i := 0; i < total; i++ {
		index := i
		lines = append(lines, g.TableRow(g.Custom(func() {
			g.Labelf("Label %d", index).Build()
			if scrollTrigger {
				if scrollIndex == index {
					imgui.SetScrollHereY(0.5)
					scrollTrigger = false
				}
			}
		}), g.Label("aa"), g.Label("bb"), g.Label("cc"), g.Label("d"), g.Label("e"), g.Label("f"), g.Label("g"), g.Label("h"), g.Label("i")))
	}
}

To Reproduce

1. Run my demo
2. You may see it haven't jump to the target. If your pc is very well, maybe you should increase rows to 10000.
