Missing clientTop and clientLeft in elements

[konomae]

Describe the bug

Missing clientTop and clientLeft in elements.

clientWidth and clientHeight exist, but clientTop and clientLeft do not.

happy-dom/packages/happy-dom/src/nodes/html-element/HTMLElement.ts

Lines 29 to 30 in bcb0225

	public readonly clientHeight = 0;
	public readonly clientWidth = 0;

To Reproduce

Here's an example.
https://github.com/floating-ui/floating-ui/compare/master...konomae:floating-ui:happy-dom-repro?expand=1

• Clone floating-ui repo
• Change jsdom to happy-dom
• Run tests

Since clientTop and clientLeft are missing, the calculation results in NaN.

stderr | index.test.tsx > floatingStyles no transform
Warning: `NaN` is an invalid value for the `left` css style property.
    at div
    at App (/Users/user/Code/floating-ui/packages/react-dom/test/index.test.tsx:680:60)

I made a small patch in the fork repo and re-run the tests, the calculation results are as expected.

Expected behavior

• clientTop and clientLeft exist.
• The calculation result should not be NaN

Additional context
