Schematic Text weight not updated when changed from Properties Panel
I'm so sorry to be reporting a bug so early after the stable release, but I only noticed it now :disappointed:
After a bit of experimenting, it seems to be in a very specific scenario, see Note 2 below.
# Description
When changing the Bold property of a Schematic Text element from the Properties Panel, the Text itself is not updated. It works for Italic and all the other Properties, but not Bold.
# Steps to reproduce
1. Create a Text element in a Schematic
2. Toggle the Bold checkbox in the Properties Panel
3. Expected: The Text's weight is changed
4. Actual result: Nothing happens
Note: After changing the Bold value and opening the Properties Dialog, the value is updated in the Dialog, but even there clicking OK doesn't update the weight.
Note 2: After changing the weight in the Dialog, everything started working as expected, for the same Text and any consecutive created Text. Also when I closed the schematic and reopened it, no bug. Even when I closed KiCad and reopened it, no bug. **HOWEVER**, after I closed the Project, restarted Kicad, and created a brand new Project, the first Text I created in that project had the exact same issue.
