BUG - but they aren't the same BWS

I wanted to compare the use of a word in different portions of scripture.
Step 1. Open a BWS on "friend" on a subset of scripture. Click on GO button. Open a second BWS on "friend" on a different subset of scripture
Step 2: Click on GO button of second BWS ... it instantly becomes the original BWS. Pretend to not be annoyed.
Step 3: Verify that you can have a second BWS if it is on a different word.
Step 4: Report as bug and wonder who didn't realize that comparing the use of a word by author or time period or other logical subset is a standard practice.
