5856 :: Karax seems to only update button when text changes. Even other onclick should be bound.

  I have a strange issue with karax. When the text in the buttons are the same (so both are "FOO") then i can not toggle back and forth. When the text in one of them is changed, lets say

   = "BAA"
  Run

  than toggle works.

  Is this a bug?

  include karax / prelude
  import jsffi, future
  
  type Comp = object
    menu: int
  
  proc createDom(comp: var Comp): VNode =
    result = buildHtml(tdiv):
      text repr comp
      case comp.menu
      of 0:
        text "Hello World!"
        button(onclick = () => (comp.menu = 1)):
          text "FOO"
      of 1:
        text "Other World!"
        button(onclick= () => (comp.menu = 0)):
          text "FOO"
      else: discard
  
  var comp = Comp()
  comp.menu = 0
  setRenderer(proc (): VNode = createDom(comp), root="ROOOT")
  Run

  I can force redraw with:

  # ...
      of 0:
        text "Hello World!"
        button(onclick = () => (comp.menu = 1; avoidDomDiffing())):
          text "FOO"
      of 1:
        text "Other World!"
        button(onclick = () => (comp.menu = 0; avoidDomDiffing())):
          text "FOO"
  #...
  Run
