Price filter possible bug

I have seen that the price filter included in woocommerce is not working properly in several cases. Let me know if I miss something in my explanations.

CASE 1: PROBLEM WITH VARIABLE PRODUCTS:
if I have a variable product with two prices, the filter price widget is working only showing the cheaper price (I have not test with more prices than two). Lets see with an example:

– The product “A” is a variable product. The Red option costs 24€ and the Black option costs 36€.
– Try to filter between 20 to 28€. “A” is showed. Ok.
– Try to filter between 32 to 40€. “A” is NOT showed. Wrong. Because the Black option costs 36€

CASE 2: Filter not showing the highest price:
The filter shows by default prices between 0€ to the highest, rounded to the enter number below. Then, if you apply filter, the highest value product sometimes is not showed. Lets see with an example:

– The product “B” costs 48,40€. The values showed in the price filter widget are from 0 to 48€. Wrong, it should show between 0 to 48,40€, or to 49€ maybe.
– If you filter, without touching the maximum price, the product “B” is not showed, what is logical, because the price is above 48€, but is weird, because is not possible to show this product with any filter.

Am I wrong in some of these problems?
