grid-template-columns (and possible others) get shortened wrongly

Possible duplicate of or at least related to #365.

Version used: 1.3.66

I have this class which basically splits a div in half:
.split-half { display: grid; grid-template-columns: calc(50% - 1rem) calc(50% - 1rem); grid-column-gap: 2rem; }
and after minifying it becomes
.split-half { display: grid; grid-template-columns: calc(50% - 1rem); grid-column-gap: 2rem; }
The second column value is removed and turns this into a very different layout.

I'm guessing this happens because the values for both columns are equal. If I change the definition to
.split-half { display: grid; grid-template-columns: calc(50% - 1rem) calc(50% - 1.1rem); grid-column-gap: 2rem; }
it works and the definition is kept. Same for using repeat(2, calc(50% - 1rem)).

Just ran into this problem as well. Any updates on a resolution?
