pasting makes code disappear

[rcrooks]

Issue Type: Bug

I think this must have something to do with the smart selection improvements, but I can't figure out what is happening. What I'm seeing is that when I place the cursor in the middle or at the end of a line and paste some code there, other code following that, sometimes on multiple lines, disappears. for example, I had this
if (video.loc.indexOf('?') > -1) {
video.loc += '&' + url_param + '=';
} else {
video.loc += '?' + url_param;
}

I copied the '=' from line 2, placed the cursor before the ; on line 4 and pasted. both the ';' and the '}' on the following line disappeared.

Is it a formatting bug? Do you have editor.formatOnPaste set?

[rcrooks]

I do have that on. Will turn it off and see if that makes a difference (though I suppose it would be a bug in the format on paste in that case).

[rcrooks]

so far, not seeing it since turning off format on paste. Will report back if that changes.

[roblourens]

Maybe from unibeautify-vscode?

[rcrooks]

That's possible, though I haven't actually seen it happen when I run the formatter, and I only run it manually. but if it recurs, I'll try disabling that.
