Duplicate CSS rule declarations not being removed when there is a comment in between

[alan-agius4]

Duplicate CSS rules declarations are not being removed when there is a comment in between the duplicate rules.

Example in the below case .mat-calendar is defined with the same CSS rules twice.

.mat-calendar {
  font-family: Roboto, "Helvetica Neue", sans-serif;
}

.mat-calendar {
  font-family: Roboto, "Helvetica Neue", sans-serif;
}

.mat-select {
  font-family: Roboto, "Helvetica Neue", sans-serif;
}

$ esbuild styles.css --minify | grep 'mat-calendar' | wc -l
 2

Output (Prettied for convenience.)

.mat-calendar {
