Test: When a work exists more than once in the program, it appears that many times on the Work list page

Ludwig van Beethoven — String Quartet No. 7 Op. 59 No. 1 "Razumovsky" (Mvt. 1)
Ludwig van Beethoven — String Quartet No. 7 Op. 59 No. 1 "Razumovsky" (Mvt. 3)
Giacomo Puccini — Madama Butterfly (Part I)
Giacomo Puccini — Madama Butterfly (Part II)
Giacomo Puccini — Madama Butterfly (Part III)

Hypothesis:

This performance will appear on the Work page as many times as the Work exists on the program.

Expected behavior: each performance appears only one time on any list page.

Razumovsky is on the program twice; it appears here twice (but should appear only once): https://lmp-test.herokuapp.com/events/works/32562/ludwig-van-beethoven/string-quartet-no-7-op-59-no-1-razumovsky-ludwig-van-beethoven?near=seattle-wa&include= 

Madama Butterfly is on the program three times; it appears here three times (but should appear only once): https://lmp-test.herokuapp.com/events/works/24365/giacomo-puccini/madama-butterfly-giacomo-puccini?near=seattle-wa&include=
