html root element not aligned properly with window inner size [Desktop wayland]

**Problem**

The size of the html root element of the Dioxus desktop app does not match the inner size of the display window.

Steps to reproduce the behavior:

If I draw a line around the maximized html element, I do not see the bottom border (screenshot below).

```css
html {
border-width: 1px;
border-style: dashed;
border-color: yellow;
height: 100%;
}
```


If I reduce the height of the html element to 99%, the bottom border is visible in some circumstances:
- With the default window size it is visible:


- However if I shrink the window it disappears:


- And when I increase the vertical size of the window the distance between the bottom of the window and the bottom border grows:


**Expected behavior**

The size of the maximized html root element perfectly matches the size of the window at all times.

**Questionnaire**

I'm interested in fixing this myself but don't know where to start.
