Repeatedly destroying and placing suspicious sand or suspicious sand gravel, part of the destruction particles turns black

When you repeatedly break and place (by repeatedly pressing the left and right mouse buttons to place and break) suspicious sand or suspicious gravel in versions 25w16a or 25w17a, some of the break particle effects become black particle break effects [In version 1.21, the particle break effect is the corresponding block particle block effect when suspicious sand or suspicious gravel is placed and broken by repeatedly pressing the left and right mouse buttons].
