- These bullet items use an em dash surrounded by spaces (" Type — Details"). The repo Markdown style guidance prefers no spaces around em dashes; using a colon here avoids that and reads cleanly.
- **System.Windows.Forms.Control** — <xref:System.Windows.Forms.SendKeys> sequential immediate modifier parsing (such as `^a^c`, `+a+c`, `%f%t`) regression is fixed. The `KeyboardToolTipStateMachine` no longer throws `KeyNotFoundException` when focus changes during a tooltip popup event.
- **System.Windows.Forms.ListBox** — `IsSynchronized` values are now correct across `ListBox` collections.
- **System.Windows.Forms.NumericUpDown** — Button rendering regression when visual styles are disabled is fixed.

- Same issue here: spaced em dash between the control name and details. Switching to a colon keeps the bullets consistent and avoids the spacing rule violation.
- **System.Windows.Forms.SplitContainer** — Transient GDI+ `ExternalException` during display-session transition when calling `RepaintSplitterRect` is now handled.
- **System.Windows.Forms.ToolStrip** — The scroll-down button no longer throws when scrolling. Indeterminate and checked `ToolStripMenuItem` icons are now visible in dark mode.
- **System.Windows.Forms.PropertyGrid** — Property Page button icon no longer changes when `LargeButtons` is toggled on high DPI. `ResetHelpForeColor` now correctly resets the foreground color instead of the background color.

- Same pattern in the remaining bullets. Use a colon after the bolded component name for consistency and to avoid spaced em dashes.
- **System.Windows.Forms.PrintPreviewControl** — `ForeColor` rendering is now correct when set to White.
- **System.Windows.Forms dark mode** — `LinkLabel` contrast in Dark Mode is improved. `TabControl` nested in `SplitContainer` now matches dark mode. `HelpProvider` text is now visible in dark mode. `ToolTip` now switches to dark mode when `SystemColorMode.Dark` is set.
