What?

When manually entering a page number in the pagination control, an invalid page number incorrectly enables the previous pagination controls, allowing the user to "access" pages below 1.

Expectations

When manually entering a page number, an invalid number should be reset to within range, and the pagination controls should be enabled appropriately:

• If it is reset to the first page, the previous controls should be disabled.
• If it is reset to the last page, the next controls should be disabled.
• If it is reset to both (that is, there is only one page), both the previous and next controls should be disabled.

Reproduction

1. Navigate to the pagination control, and enter a page number out of range (e.g. 0).
   
2. Note that the value will reset to a number within range (e.g. 1), but that the "First page" and "Previous page" buttons will be enabled.
   
3. Pressing the "First page" button will reset appropriately to the first page
   
4. Pressing the "Previous page" button will move backwards through non-existent pages
