Review Comment:
   I think the issue here is that the `getValueCapacity` depends on the 
capacity of the `viewBuffer` and `validityBuffer`, so in the while loop, when 
just one is changed, and the other value is kept the same, the minimum will 
always be the unchanged value. So I think the main issue is the error in that 
function. Thank you for this test case, I don't think the existing test cases 
covered this case.
