Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.4.0
• VSCode version: 1.33.0
• OS: Windows_NT x64 10.0.17763

Start by reproducing the issue in VSCodeVim 1.4.0 on Windows with a Chinese input method, following the listed timing and double-click steps. Inspect the handling of insertModeKeyBindings and keyboard input around the input-method switch. Done means the previous input is ignored after switching and double-clicking J exits insert mode without retaining J or moving the cursor.
