[Bug]: [blocklist] can't remove [type='button'] selector

[chenqiangkobe]

Describe the bug

i I want to remove [type='button'] selector.

preflight.css:
button,
[type='button'],
[type='reset'],
[type='submit'] {
-webkit-appearance: button; /* 1 /
background-color: transparent; / 2 /
background-image: none; / 2 */
}
my postcss.config.js :
blocklist: ['[type='button']', /^[type='button']/]

finally， [type='button'] exists in the index.css file. The blocklist configuration doesn't work, my blocklist expression is wrong?
