page B is all tabs pages, and C is the navigator component jump page in page A; now load Mini Program to enter page A first, click tabs page B in the second step, click on page An in the third step, and click on the navigator component in page An in the fourth step to enter the C page. The problem is that the tabs page will be displayed before entering the C page. Doesn"t tabs page switching delete all previous pages from the page stack? why do you first display previously opened tabs pages?
