[TYPO3-core] Gremlin #1690: nav_frame is sometimes out of sync with the selected page

[Sebastian Kurfuerst]

Hi Michael,

<krümelkacker>
      * both wraptitle functions are missing the tab before { I think.
      * on the jumpTo function, there is an empty comment behind
</krümelkacker>
      * you initialize this.currentBank="0"; - so it is a string, but
        you set it as a number if i saw it correctly. why not set
        this.currentBank=0?

Otherwise, +1

I didn't test if it works, but we did this together during zap the
gremlins - so I believe it does.

Good work,
Greets, Sebastian
