Cannot manipulate text selection in diagnostics popovers using keyboard shortcuts

[injust]

Summary

Description

After selecting text in a diagnostics popover, the standard text selection keyboard shortcuts should be usable, e.g. shift-left/right, shift-opt-left/right, and shift-cmd-left/right.

Steps to reproduce:

1. Write some code that produces an inline diagnostic error/warning
2. Hover the mouse cursor over the line to show the popover
3. Move the mouse cursor over the popover
4. Click-and-drag to select some text
5. Use keyboard shortcuts to manipulate the selected text

Expected Behavior: The keyboard shortcut manipulates the selected text in the popover Actual Behavior: The keyboard shortcut manipulates the buffer text, closing the popover
