Description
Describe the bug
When hovering over the beginning HTML tag of a pair, in Normal Mode, a second cursor appears on the closing tag. When switching to Visual Line Mode, with SHIFT + V, VS Code shows the message "ModeHandler: unexpected selection mode. selectionMode=4" and does not switch to Visual Line Mode.
To Reproduce
Create an HTML tag pair (i.e opening and closing div tags). In Normal Mode, place the cursor on either of the tag pair. A second cursor will appear on the opposite tag. Try switching to Visual Line Mode with SHIFT + V, the message "ModeHandler: unexpected selection mode. selectionMode=4" will appear and will not switch to Visual Line Mode and highlight the line.
Expected behavior
When placing the cursor on a beginning or closing HTML tag element, a second (or dual cursor) should not appear on the opening and closing HTML tags, and switching to Visual Line Mode with SHIFT + V should switch the editor to Visual Line Mode.
Environment (please complete the following information):
- Extension (VsCodeVim) version: 1.12.2
- VSCode version: 1.41.0
- OS: macOS Mojave 10.14.6

Research direction
Reproduce the issue in VSCodeVim with an HTML tag pair, Normal Mode, and Shift+V, then trace the selection-mode handling that reports selectionMode=4. Done means tag matching no longer creates the conflicting dual cursor and Visual Line Mode switches normally.
