For the above issues, the solution is need to remove the "--wp-global-header-height" variable in the below CSS.

Added:

.wp-code-block-button-container {
  position: sticky;
  top: calc(var(--wp-admin--admin-bar--height));
  z-index: 1;
  display: flex;
  justify-content: right;
  padding: 1rem;
  background: #fff;
  border-width: 1px 1px 0;
  border-style: solid;
  border-color: #dcdcde;
  border-top-left-radius: 0.3em;
  border-top-right-radius: 0.3em;
}
