The core infrastructure for vertical tabs has been removed from upstream
* Split tab - CompoundTabContainer which contains pinned contrainer and
unpinned container separately is removed.
* Scrollable tab strip support was removed - TabStripScrollContainer was
removed.
This PR temporarily make Brave buildable and disables vertical tab strip
support
As CompoundTabContainer is gone, rework BraveTabContainer to handle both
pinned and unpinned tabs.
Previously, we had CompoundTabContainer which contains two TabContainers
, one for pinned tabs and the other for unpinned tabs. And TabContainer
for unpinned tabs had a ScrollView to allow scrolling when there are
many unpinned tabs.
But now, as CompoundTabContainer is removed, we need to handle both pinned
and unpinned tabs in BraveTabContainer. Plus, we should support scrolling
feature for unpinned tabs.
But adding scroll view to BraveTabContainer causes various issues as
it manipulates view hierarachy, which upstream code is not aware of.
As a result, it'd require many changes from our side to make it work.
So instead of adding scroll view, we directly handle scrolling logic
inside BraveTabContainer. BraveTabContainer calculates visable area
for unpinned tabs and sets clip rect accordingly. It also handles scroll
events and update unpinned tabs position based on the offset.
