Why is the Teemo Shroom bug (ward remnants detonate shrooms) not being fixed?

Bugfixes Patch 5:23 Fixed a number of broken interactions between the Summoner Spell cooldown reduction effects from Boots of Lucidity, Enchantment: Distortion and the Insight mastery Sivir's W - Ricochet now continues bouncing to new targets after Sivir dies Restored on-hit particles for Zac's W - Unstable Matter Flashing forward immediately after casting Syndra's E - Scatter the Weak no longer changes the cone's area of effect Fiora's W - Riposte now properly blocks vision-granting effects of abilities she successfully parries Thresh can once again purchase Runaan's Hurricane Valor can no longer purchase Tiamat or its upgrades. Sorry, Quinn.

i dont understand. this is gamebreaking. i dont know how many shrooms i have detonated myself just because i destroy a ward and then the shards detonate the shroom. why wont you fix this obvious bug? @scarizard
