When working with a big piece of text, I sometimes scroll down and copy some text into another tab. When switching back to the first tab, both the input and the output pane is back on top. So I don't know where I was working just now.

Describe the solution you'd like
After tab switching, scroll position should be remembere

I noticed a difference in behaviour and like to have a clarification if it is a bug or works as intended.
If you invoke an app with --help [command] the command is not executed and the help of the command is shown.
If you invoke an app with --version [command] the command is executed and no version information is shown.

Everything in diagrams.css should be scoped to some wrapping css class, because as is it cannot be bundled with the rest of an app's css because of styles like this:

div {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

svg {
    width: 100%;
}

This is related to #410 and #859, we currently only support a limited subset of possible values for RDATE, but we should support all the parameters in RDATE, the grammar for which is set out in RFC 5545:

       rdate      = "RDATE" rdtparam ":" rdtval *("," rdtval) CRLF

       rdtparam   = *(
                  ;
                  ; T
