EasyList China in uBlock blocks Gmail contents

[v998]

Comparison for both ABP and uBlock only enabled the same filter
(all emails contents are blocked) (tested on different emails and gmail accounts)
ABP EasyList China only:

uBlock  only enabled CHN: EasyList China (中文) (adblockplus.org)

Not knowing why that happens..

There is this filter in EasyList China: ~car.kdslife.com,kdslife.com,pchome.net##div[class^="ad"].

~car.kdslife.com##div[class^="ad"] would normally mean hide div[class^="ad"] everywhere except on car.kdslife.com, as per ABP doc. But as per ABP's behavior, it appears the real definition is more complicated.
