bug: tabindex adverse effect after adding clear-input="true"

Bug Report

Ionic version:
As per latest on CDN

Current behavior:
When you fill an input item that has clear input set to true and then press tab the focus does not move to the next element. (even when tab index is set on the inputs)

Expected behavior:
Perhaps this is intended behaviour but I would expect the next input to be focused after you have finished writing in an input.

Tabbing to an element that already has text in it is working perfectly (please don't change this). It is just leaving the input that seem to require an additional un-needed tab.

Steps to reproduce:
Any ion-items in a row with clear input.

从链接的 CodePen 复现开始，检查 Ionic input 和 clear input 在 Tab 导航中的行为。使用包含 clear input 的 ion-item 行确认该行为，然后验证编辑后按 Tab 会移动到下一个元素，同时不会改变已有文本的 input 的现有行为。
