Sliders, Drags: Fixed using hexadecimal display format strings (pretty much never worked). (#5165, #3133) 

Ditched unnecessary code. When transitioning from float in 3e8087458 we added an unnecessary path there, which evolved in c5fb92955.

or interacting with a game/3D view).
- Clipper: Fixed a regression in 1.86 when not calling clipper.End() and late destructing the
clipper instance. High-level languages (Lua,Rust etc.) would typically be affected. (#4822)
- Sliders, Drags: Fixed using hexadecimal display format strings (it never worked). (#5165, #3133)
- IsItemHovered(): added ImGuiHoveredFlags_NoNavOverride to disable the behavior where the
return value is overriden by focus when gamepad/keyboard navigation is active.
- InputText: Fixed pressing Tab emitting two tabs characters because of dual Keys/Chars events being
