Ivanchuk navbar - broken coloring

Cc @epwinchell

That's not intentional, right?
The violet navbar that abruptly stops and changes into the usual blue gradient.

[himdel]

clue: it's not present in lower resolutions, halfscreen has the blue gradient all the way,
but full 1920 width breaks this way

[epwinchell]

@himdel That's a bug

[chessbyte]

@epwinchell is this fixed on jansa?

[epwinchell]

@chessbyte If I recall, this was an Ivanchuk only bug. @himdel can confirm.

[himdel]

It was definitely an ivanchuk only bug when we planned to have the new menus in jansa.

That didn't happen.

Jansa is different because of #6637,
but the actual color constants in jansa are the ones #6990 changed from.

I'll try to get a working jansa to test this :)

[himdel]

So,
ivanchuk: fixed (#6990)
jansa: not a problem (likely #6637)
master: no navbar (#6963)

jansa-1-beta-1 (small):

jansa-1-beta-1 (large):

(There is an issue - the navbar won't adapt to smaller resolutions, but that's not this issue, or a regression.)
