Middle mouse button scrolling breaks when click+holding on a image within release notes.

[Steve-Fry]

Issue Type: Bug

1. Open VSCode
2. Open release notes (Control+Shift+P --> Release Notes)
3. Click and hold middle mouse button while mouse is over an image.

Expected behavior:

• Screen will scroll according to offset of mouse postion from inital mousedown position.

Actual behavior:

• No scrolling occurs.
• All mousewheel based scrolling is not possible from this time on. This is only returned to normal functionality after switching tabs/reloading editor.

GIF Example

Events:

• Left Click - Clear existing selected text
• Middle Mouse Click on text
• Middle Mouse Click on image
• Middle mouse Click+Hold on text
• Middle mouse Click+Hold on image

Also what can be seen on this gif is another bug(I don't believe that it's intended behaviour): scrolling the release notes with MMB held selects the text. Same effect as holding LMB over text and scroling with keyboard arrow keys. When VS Code doesn't have focus, selection still appears and MMB scrolling doesn't work. - Windows, idk about other OSes.
