Developing node crashes app

[Traroth]

On some large documentations, like Spring or Java SE 17, Zeal crashes when I click on the develop "+" on the left panel.

To reproduce the issue:

-Click on the documentation in the left panel to display the doc's home
-Click on the "+" of given doc in the left panel to develop the summary

It seems to work for a second, then crashes.

If I do it the other way around, first click on "+" and the on the main title, it develops the summary tree and displays the home, but it still crashes after a few seconds.
