'Delete' button doesn't appear on brave://history when using the search bar at the top

[onmyouji]

Description

Normally when you check the box next to an item on brave://history, the 'Delete' button will appear at the top right.

But when you search something specific using the search bar, the 'Delete' button doesn't appear when you check the box. I initially thought that I have to delete the checked items one by one. But turns out I can still delete multiple items by using 'Delete' key on my keyboard. Still this is not really good in terms of UI and can be confusing for users.

For comparison, on Chrome the 'Delete' button still appears when you use the search bar.

Steps to Reproduce

1. Open History (Ctrl+H) or type brave://history
2. Click the Search button at top right, then type your search query. It will display the search results.
3. Check the box next to an item. The 'Delete' button doesn't appear.

Actual result:

The 'Delete' button doesn't appear.

Expected result:

The 'Delete' button should appear.

Just encountered this one and had to go to inspect mode to access the Cancel and Delete options for my selections. Looks like the cr-toolbar-selection-overlay should take index priority over the cr-toolbar #main-toolbar.

I believe this is happening because the br_toolbar Polymer component is on top of the Cancel and Delete buttons (and the UI showing how many items matched search)

Labeled as P3 since this is broken functionality
