When the "Use previous version of Microsoft IME" Windows option is enabled, jumping while sneaking fails

When the Windows option "Use previous version of Microsoft IME" is enabled, you cannot jump while sneaking (I only tested this under the Chinese input method). This bug does not exist from 26.3-snapshot-4 to 26.3-snapshot-8. I suspect it is because during these snapshots, when no text field is selected in the game, the IME state strictly does not change. However, in 26.3-snapshot-3 and earlier versions, the IME state could briefly change when no text field was selected; in 26.3-snapshot-9 and newer versions, the IME state can fully change when no text field is selected. Therefore, this bug exists in earlier versions and newer versions. Similarly, during 26.3-snapshot-4 to 26.3-snapshot-8, the bug where pressing Ctrl + Space only sprints but does not jump also mysteriously does not exist; the bug where pressing W, A, S, or D to move brings up the IME candidate window also mysteriously does not exist. Therefore, I believe that to fix the bug described on this page: "When the Windows option 'Use previous version of Microsoft IME' is enabled, you cannot jump while sneaking," as well as other IME-related bugs, perhaps the simplest solution is to make the IME state strictly not change (when no text field is selected).

Issue update: I suspect that this bug and other IME-related bugs do not exist in Vulkan! Because I once said in another issue of mine:

After asking a mod developer and having two of my friends help test, the following new facts have been established, since SDL3 replaced GLFW in 26.3-snapshot-4: When using OpenGL: before 26.3-snapshot-9, this bug does not exist, and the IME state strictly does not change (when no text field is selected). When using Vulkan: this bug does not exist up to the latest version (26.3 release), because the IME state always strictly does not change (when no text field is selected). Therefore, this bug and other IME-related bugs do not exist in Vulkan!
