Multi-row Issue Jump

[Mgldvd]

hi, the multi row is jumping, already disable all other plugins and try only with tabutils.

I stay in 52.0.2 like a lot of users because of that...

The problem seems to be because of the new tab-label-container hbox, and the CSS :

.tab-label-container {
  overflow: hidden;
}

which send overflows at each mouse movement on a tab. So the fix I found in tabutils-mt.js is:

  tabutils.addEventListener(gBrowser.mTabContainer, "overflow", function(event) {
    if (event.target.tagName == "tab") {
      event.stopPropagation();
      return;
    }
    this.enterBlockMode();
  }, false);

A problem stays with the newtab button which doesn't want to stay next to the last tab, and goes right (after hesitation lol).

Just added that to fix the "new tab button(s)" behaviour:

#tabbrowser-tabs[multirow] + #new-tab-button {
  display: none;
}

#tabbrowser-tabs[multirow] .tabbrowser-arrowscrollbox > .tabs-newtab-button {
  visibility: visible;
}

Edit : It's a little buggy sometimes.
