It should set width/height to the exact number; or at least the nearest number.

Actual Behavior

It falls back to the default value of the property that has a decimal number.

No response

Additional Information

It just doesn't respect the decimal number.
As example, if the width of the BrowserWindow is set to 3.14, it uses the default value; which is 800.

This is not a bug; it's a feature request. As it stands, you owe Electron a whole-pixel value here and it's your job to round it.

This was actually addressed as a side effect of #42056 - as of this PR, you can pass in double values and they will be rounded to the nearest number and set to that.
