There is a part of the code in PDFViewer that I don’t fully understand

[kkHAIKE]

pdf.js/web/pdf_viewer.js

Lines 1665 to 1678 in 9bf9bbd

	let stillFullyVisible = false;
	for (const page of visiblePages) {
	if (page.percent < 100) {
	break;
	}
	if (page.id === currentId && isSimpleLayout) {
	stillFullyVisible = true;
	break;
	}
	}
	this._setCurrentPageNumber(
	stillFullyVisible ? currentId : visiblePages[0].id
	);

According to the logic of this referenced code, stillFullyVisible should represent that the current page and all previously visible pages must be fully displayed. However, I think it should only require the current page to be fully displayed.
