I'm seeing an issue in the latest release of Firefox (103.0.2) & Firefox developer edition (104.0b10) when working with a manifest v2 web extension. The issue is not present in Firefox Developer edition (100.0b9) and below.
When calling browser.windows.create() - passing valid options for height & width is resulting in a completely invalid and unexpected size for the resulting window. The code to reproduce the behavior is below.
This is being run in a background script of the extension.
```
const width = props.width ?? Math.round(window.screen.width * 0.8);
const height = props.height ?? Math.round(window.screen.height * 0.8);
// center by default
const top = props.top ?? Math.round(window.screen.height / 2 - height / 2);
const left = props.left ?? Math.round(window.screen.width / 2 - width / 2);
console.log(
`In openWindow width ${width} height ${height} top ${top} left ${left}`
);
const newWindow = await browser.windows.create({
url: props.url,
width,
height,
top,
left,
type: 'popup',
});
```
The console.log result is
```
In openWindow width 3072 height 1728 top 216 left 384
```
These are valid numbers for the screen I am working on (standard 4k displays). I am running 3 screens, all hiDPI - two are default 4k external monitors, the third is the built in laptop display.
I have not yet tested the result on other operating systems - however I am running macOS Monteray v12.4.
When running in version 100.0b9 and below, I see a centered screen ~80% of the monitor width and height appear. When I run in the current versions, I see the window briefly flash at full screen, then immediately downsize to a very small window in the upper left corner.
Please see a brief recording of the working version of Firefox Developer Edition compared to the broken version of standard Firefox here:

I am running the exact same extension build in both versions.
