Guake always opens new window on link click

[rafnov]

When trying to open link from Guake it always opens new browser Windows with two tabs, not regarding it another browser window is opened or not.
1st tab of new window is always file:///home/rav/%u
2nd tab is proper link.
Checked that on Tilda and Xfce Terminal on XFCE - they do fine, so its not browser upstream (set to always open new tab instead window) and not DE issue.
Only Guake does that. Tried to install from git but failed. Some conflicting files exist.

Please fix, or tell me how to fix.
Guake is not configurable about links like Tilda. But Guake works everywhere better as drop down terminal, than Xfce or Tilda terminals.
