+  
+  * refactor(material/chips): remove button is too small

+  Fixes b/286959517
+-  updates chip remove button touch target to increase accessibility of the button especially on touch/mobile devices.
+  
+  * fix(material/chips): chips remove touch target is too small to be accessible
+  
+  Updates Angular Components Chips component by increasing its
+  .mat-mdc-chip-remove::after styles to increase the size of the
+  touch target to make it more accessible/clickable.
+  
+  Fixes b/286959517
+  
+  * refactor(material/chips): fix lint errors
+  
+  Updates fix for Angular Components Chips component where there
+  were lint formatting errors.
+  
+  * refactor(material/chips): replace px with _trailing-icon-size variable
+  
+  Updates previous Angular Components Chip component fix and makes it
+  adaptable by swapping the hard-coded 18px offset to equal the
+  variable for -icon-size.
+  
+  * refactor(material/chips): updates touch target centering method
+  
+  Updates previous Angular Component Chip component fix which
+  added padding to the ::after pseudo-element and attempted to
+  calculate centering. Changes calculation based on using
+   with padding values countered
+  with margin negative values to center the touch target.
+  
+  * refactor(material/chips): updates ::after styles and fix lint errors
+  
+  Updates Angular Component Chips component fix to change ::after
+  background property changes to be background-color specifically to
+  avoid overriding background-clip styles. Suppresses lint warning
+  material/no-prefixes for background-clip since it's majority
+  compatible with browsers.
+  
+  Fixes b/286959517
+  
+  (cherry picked from commit d6aed804460d4b75082d7d04e051f2cae9b4f8f6)
