Setting undefined on property of useElementStyle is not working.

[shtse8]

const sidePanelContent = ref()
const { x: windowX, y: windowY } = useWindowScroll()
const { width, height } = useWindowSize()
const { x, y, top, right, bottom, left } = useElementBounding(sidePanelContent)
const { style, stop } = useElementStyle(sidePanelContent)
watch(windowY, (current, last) => {
  const direction = current > last ? 'down' : 'up'
  console.log('direction', direction)
  console.log(x.value, y.value, top.value, right.value, bottom.value, left.value)
  // styleObject.top = top
  console.log('height', height)

  // style.position = top.value < 0 && bottom.value > height.value ? 'relative' : 'sticky'
  // if (bottom.value < height.value || top.value > 0) {
  //   const marginTop = parseFloat(style.marginTop ?? 0)
  //   style.top = `${-top.value + marginTop}px`
  // }
  if ((top.value > 0 && direction === 'up') || (top.value < 0 && direction === 'down')) {
    console.log('stick to top')
    style.position = 'sticky'
    style.marginTop = undefined
    style.top = 0
    style.bottom = undefined
  }
  else if ((bottom.value < height.value && direction === 'down') || (bottom.value > height.value && direction === 'up')) {
    console.log('stick to bottom')
    style.position = 'sticky'
    style.marginTop = undefined
    style.top = undefined
    style.bottom = 0
  }
  else {
    console.log('floating')
    style.position = 'relative'
    style.marginTop = `${-top.value}px`
    style.top = undefined
    style.bottom = undefined
  }

  console.log(style)
})

style is still there even setting it to undefined.

Hey, could you provide an example of how you would like to use it on a sandbox?

Here is a link to a blank sandbox to help it: https://stackblitz.com/edit/vue-zj2zpq?file=src%2FApp.vue

Would you be able to provide a reproduction? 🙏

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritize it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

A link to a stackblitz project or public GitHub repository would be perfect. 👌

Please ensure that the reproduction is as minimal as possible.
