SVG rectangles pushed together in Firefox but not Chrome/Safari

I've got an SVG that I've animated. It works fine (or at least as well as it needs to for now), however when I look at it in Firefox, the 2nd and 3rd rectangles of the SVG are squashed together.

No idea why, as it's fine in Chrome/Safari. I think it may be something to do with the transform: scaleY, but not 100% sure.

If anyone can tell me why/how to fix, that'd be great.

Sidenote: If anyone knows how to sort the smoothness when it stops/starts, awesome, but that may be another question.

Codepen: https://codepen.io/Will5592/pen/WPQQKB

const svg = document.querySelectorAll('rect');

svg.forEach(item => {
  item.addEventListener('click', (e) => {
    svg.forEach(i => i.classList.toggle('animation-on'))
  })
})
body {
  height: 80vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

svg {
  width: 25vw;
  height: 25vh;
  cursor: pointer;
}

.animation-on {
  animation: updown 0.75s infinite linear;
}

rect {
  transform-origin: 0 50%;
  transform: scaleY(0.75);
}

rect:nth-child(1) {
  animation-delay: 0.05s;
}

rect:nth-child(2) {
  animation-delay: 0.075s;
  animation-duration: 0.65s;
}

rect:nth-child(3) {
  animation-delay: 0.10s;
  animation-duration: 0.75s;
}

rect:nth-child(4) {
  animation-delay: 0.125s;
  animation-duration: 0.75s;
}

rect:nth-child(5) {
  animation-delay: 0.15s;
  animation-duration: 0.85s;
}

@keyframes updown {
  0% {
    transform: scaleY(0.5);
  }
  50% {
    transform: scaleY(1);
  }
  100% {
    transform: scaleY(0.5);
  }
}

As mentioned in my comment above. Using whole numbers for the x coordinate seems to be a workaround for this issue.

In the example below, I've multiplied all coordinate values by 10 and rounded off the x coordinate.

const svg = document.querySelectorAll('rect');

svg.forEach(item => {
  item.addEventListener('click', (e) => {
    svg.forEach(i => i.classList.toggle('animation-on'))
  })
})
body {
  height: 80vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

svg {
  width: 25vw;
  height: 25vh;
  cursor: pointer;
}

.animation-on {
  animation: updown 0.75s infinite linear;
}

rect {
  transform-origin: 0 50%;
  transform: scaleY(0.75);
}

rect:nth-child(1) {
  animation-delay: 0.05s;
}

rect:nth-child(2) {
  animation-delay: 0.075s;
  animation-duration: 0.65s;
}

rect:nth-child(3) {
  animation-delay: 0.10s;
  animation-duration: 0.75s;
}

rect:nth-child(4) {
  animation-delay: 0.125s;
  animation-duration: 0.75s;
}

rect:nth-child(5) {
  animation-delay: 0.15s;
  animation-duration: 0.85s;
}

@keyframes updown {
  0% {
    transform: scaleY(0.5);
  }
  50% {
    transform: scaleY(1);
  }
  100% {
    transform: scaleY(0.5);
  }
}
