I haven't yet tested whether removing this is an issue (likely is). The logic here is quite convoluted.

Fixed by 5724733. It's touching some scary code but I think it makes sense.

I've added tests in my other PR to ensure the issues linked above are specifically fixed (see cf31661), worth adding in this PR. For ppy/osu#25850, I would just disable searching in |

Definitely better than the other approach, let's see how this pans out 😄 . |

Fixes ppy/osu#25769
Fixes ppy/osu#26079 (likely)
Supersedes / closes #6095
Closes #6097 (note that ppy/osu#25850 is likely not fixed by this and will need reimplementation)
By extracting focus-management logic out of
InputManager, we can implement something akin to a focus trap. Components can trap the focus management (ChangeFocus()/TriggerFocusContention()) of their subcomponents to add supplementary logic.This PR features a partial redesign of
Dropdownmaking use of this. There are two components wanting to manage focus here - theMenuand theTextBox.Menu's focus is trapped byDropdownand reduced to a no-op.TextBox's focus is trapped withinDropdownSearchBoxto perform additional functionality such as opening the dropdown on focus, selecting items on commit, clearing text on escape, etc.This is not a breaking change, but I've obsoleted
InputManager.TriggerFocusContention()andInputManager.ChangeFocus()partially to make this easy to test.
