I tried to make auto-complete input with mat-chip in Material Design. In this situation, I am using official Angular manual or StackBlitz on website. Everythings works, everything looks good as it's supposed to be on Google Chrome and also Opera browsers but chips' matChipRemove looks weird on Firefox browser. I shared images on browsers for better understanding.
Google Chrome / Opera Browser (Nicely)
Firefox Browser (Weird. There is a box behind icon.)
How does the code that works well in Google Chrome/Opera does not work in Firefox? What is causing this problem?
