Grid layout breaks if it contains horizontal

**Describe the bug**
`Grid` layout show incorrect margin when `ui.horizontal()` is used inside as a cell.

In the following screenshot:
- Row 1 is slightly away from the upper border of the window, and covers some parts of Row 2.
- There is a gap between Row 2 and Row 3.

***My guess for the reason***

> Note: I have not checked or verified if this is the actual problem, and it is **only** my best guess.

Looking at the first row only, I'm thinking that egui may have pre-calculated the size of `horizontal` once and put Label 1 into the correct position, however egui falsely shifted the `horizontal` downwards as well to match the top of Label 1. This applies to the rest of the rows.


**To Reproduce**
Here's the code used to reproduce the problem
```rust
egui::Window::new("Window").show(ctx, |ui| {
egui::Grid::new("grid_test").show(ui, |ui| {
ui.label("Label1");
ui.horizontal(|ui| {
ui.label("This is the longest label\nwith 4 lines\nthis is the 3rd line\nand the last line here.");
});
ui.end_row();

ui.label("Label2");
ui.horizontal(|ui| {
ui.label("This is a shorter label\nwith 2 lines only.");
});
ui.end_row();

ui.label("Label3");
ui.horizontal(|ui| {
ui.label("This is a long label\nwith 3 lines\nand here is the last line.");
});
ui.end_row();
})
});
```

**Expected behavior**
The grid layout should function as *normal*, with correct margins between each line.
