Current behavior 😯

While using the firefox browser, when the snackbar opens, the text starts a few pixels down, then jumps to the correct position. When closing the snackbar, the text lowers again, then the snackbar closes.

Expected behavior 🤔

The text should be centered vertically in the snackbar, and not move.

Steps:

  1. Use firefox browser
  2. Trigger snackbar open
  3. Observe the text starting lower, then moving up
  4. Close the snackbar
  5. Observe the text moving down, the snackbar close
Context 🔦
