Have you checked if it needs to be modified in any SCSS file?

OT: What a funny color value "#cacaca" chose the Magento team. This word in some languages means poop/shit.

Yes, the OM theme had no override for those styles.

Even I approved this PR, I noticed that it creates issues. Below are screenshots that prove it. Aheadworks Z-Blocks extension relies on the "select.mutiselect option" in boxes.css.

If "Use parent values" is checked, you can see that the text is no longer visible.

If "Use parent values" is unchecked then it becomes visible

We should revert this PR or remove the color property / change the color value / add the background color e.g #fafafa, here is the effect below

This is how it looks the multiselect reverting this PR

It is obvious that we did not check the scenario when all options are selected. When they are not selected the background is white, and when they are selected the background is gray. that shadow made the text visible.

or we can use a soft shadow

text-shadow: 1px 1px 1px #000
