Treeview disappears while in TechDraw page view

[decryptedchaos]

Is there an existing issue for this?

Problem description

I explicitly prefer the TreeView over the combo view, but using it with TechDraw is very painful to the point that you have to either switch back to the part design page to add new views to the page or enable combo view..

Here is a video of the behavior

I will check this shortly, sorry i don't check github daily.. I usually check for replies 24 hours after my post, and then my ADHD kicks in and i forget..

I suspect it works here because you have it floating, mine is docked and i suspect the window gets created differently programmatically docked vs floating. Also, while docked it uses transparency which it doesn't use when floating which could also be the cause.

Yes, I can confirm that the issue still exists on the weekly snapshot. It looks identical to the video clip in my OP so I see no need to post another.

Please note what I referenced above, that my Tree view is docked as a panel (or whatever you call it when its transparently embedded on the left side like shown..

For further insight I can show this, when I'm in the normal Part Design view Tree View panel is checked, but when I go to the TechDraw page, Tree View gets forcefully unchecked and cannot be checked as shown here.. then when returning to Part Design it suddenly rechecks itself..
