Sorry for the late review.

The ignore property of label and labelLine is updated in

echarts/src/label/labelStyle.ts

Line 250 in ad3a07a

stateObj.ignore = !stateShow;

echarts/src/label/labelGuideHelper.ts

Line 623 in ad3a07a

stateObj.ignore = true;

Especially the labelLine, it has complex logic to determine if it can be shown when label is not shown. But for some reason it fails when switching from show to hide in the emphasis state.
