Incorrect script version/description in script submenu

[Klaster1]

What happens:
Previous script version/description is shown for current opened script submenu.

How to reproduce:

1. Install several scripts with description in meta.
2. Navigate to script 1. Remember what description says.
   
3. Navigate back using the arrow left to the script title.
4. Open another script submenu, see this:
   

The second script description should look like this:

All of the scripts above were installed at least a week ago.

GM version: 4.4.0
FF version: 60.0.1

The problem is the use of rv-if.

greasemonkey/src/browser/monkey-menu.html

Lines 128 to 136 in 18e21a4

	<p rv-if="activeScript.description">
	<b>{'description'|i18n}</b> {activeScript.description}
	</p>
	<p rv-if="activeScript.version">
	<b>{'version'|i18n}</b> {activeScript.version}
	</p>
	<p rv-if="activeScript.homePageUrl">
	<a rv-href="activeScript.homePageUrl">{'homepage'|i18n}</a>
	</p>

Changing to rv-show resolves the problem.
