decorations don't get drawn on reload and don't work for the first command entered

[meganrogge]

We don't persist any command information on reconnect currently, at the beginning we decided we couldn't have them live on the pty host where we would have got this for free (though there were the sync problems that would have been worse).

[meganrogge]

cannot repro anymore - likely due to this change

vscode/src/vs/workbench/contrib/terminal/browser/xterm/decorationAddon.ts

Lines 75 to 77 in ee7961d

	if (this._capabilities.has(TerminalCapability.CommandDetection)) {
	this._addCommandListener();
	} else {

to verify, make sure on reload:

• decorations don't persist
• run a command - it should have the decoration by it

[Tyriar]

This should still be happening because we don't get the command start sequence for the current command of any of the old command data.
