:inherit-props seems to not consider global properties.

Testcase:

# Create a global property

#+PROPERTY: HOURLY_RATE 150

* Top 1
** Sub 1A
# here we should get the global property, but do not
   :LOGBOOK:
   CLOCK: [2021-09-26 Sun 12:25]--[2021-09-26 Sun 13:25] =>  1:00
   - I did some tasks
   :END:

** Sub 1B
* Top 2
  :PROPERTIES:
  :HOURLY_RATE: 110
  :END:
** Sub 2A
# successfully inherit from "Top 2"
   :LOGBOOK:
   CLOCK: [2021-09-26 Sun 21:26]--[2021-09-26 Sun 22:26] =>  1:00
   - I did some other tasks
   :END:

** Sub 2B
   :PROPERTIES:
   :HOURLY_RATE: 90
   :END:
# override Top 2
   :LOGBOOK:
   CLOCK: [2021-09-26 Sun 18:30]--[2021-09-26 Sun 19:00] =>  0:30
   - Attended a meeting
   :END:

#+BEGIN: clocktable :scope file :maxlevel 2 :properties ("HOURLY_RATE") :inherit-props t
#+CAPTION: Clock summary at [2021-09-26 Sun 22:48]
| HOURLY_RATE | Headline     |   Time |      |
|-------------+--------------+--------+------|
|             | *Total time* | *2:30* |      |
|-------------+--------------+--------+------|
|             | Top 1        |   1:00 |      |
|             | \_  Sub 1A   |        | 1:00 |
|         110 | Top 2        |   1:30 |      |
|         110 | \_  Sub 2A   |        | 1:00 |
|          90 | \_  Sub 2B   |        | 0:30 |
#+END:

I expect that "Sub 1A" will show the global HOURLY_RATE of 150, but it is empty.
