Start by reading ValidationMessageBubble.java around lines 49-54 and trace the HTML popup path that calls createAndShow. Reproduce the popup crash and investigate why org.chromium.components.web_contents_delegate_android.R$layout is unavailable; done means the popup no longer triggers the reported NoClassDefFoundError or fatal abort.
