"Hold SHIFT to enable Docking window" tooltip inherits NextWindowData

[cfillion]

Version/Branch of Dear ImGui:

1.89.9-docking – 1.90.5-docking

Details:

Since 300464a, Begin shows a tooltip when io.ConfigDockingWithShift is enabled and the left mouse button is down without moving for >1s.

However it does so before clearing NextWindowData, which causes the tooltip to inherit any SetNextWindowSize or SetNextWindowSizeConstraints and display with an inappropriate size.

Even if it was correctly sized, it is quite surprising to have a tooltip show up in the middle of the window that wasn't intended by the application/tool/script developer: https://i.imgur.com/hGw49go.gif.

Screenshots/Video:

Minimal, Complete and Verifiable Example code:

ImGui::GetIO().ConfigDockingWithShift = true;

ImGui::SetNextWindowSize(ImVec2(256, 256));
// ImGui::SetNextWindowSizeConstraints(ImVec2(884, 626), ImVec2(2652, 626));
ImGui::Begin("My window");
ImGui::End();
