Chromium change: https://source.chromium.org/chromium/chromium/src/+/57a7761b2055997dccd9b566e1c42226734a1dbe [Tab Group] Fix getTabGroupCount for tab groups with size 1 TabGroupModelFilter wasn't correctly tracking tab groups with size 1. Increment when: * Creating a single tab group. * Adding a single tab that is in a tab group. Decrement when: * Closing the last tab in a group rather than when size becomes 1. * Removing the last tab from a tab group with size 1. Modify logic when adding a tab to the tab model as part of a group so that the group is created later and we can properly signal if a new group was created or not. Bug: 41496693
