ID 585847 - [C] A "Map maximum size exceeded" error occurs when importing or creating panels if "Default Flix Panel Duration" has been enforced

Problem summary:
A "Map maximum size exceeded" error occurs when importing or creating panels if "Default Flix Panel Duration" has been enforced
 
This issue applies to Show and Studio level enforcements.
 
Customer reported version:
Flix 7.0.2
 
Customer reported platform:
macOS 14 Sonoma
 
Steps to reproduce:
1) Launch Flix and open a Show's Settings
2) In the General tab, enforce the Default Flix Panel Duration preference with any value:

3) Close and reopen the Flix Client. This step is optional if the preference has been enforced at the Studio level instead of the Show level.
4) Create a new Sequence Revision, and repeatedly add new blank panels.
5) Observe how the total number of Frames in the Revision does not increase additively (12+12+12 = 36), and instead increases by concatenation (12+12+12 = 121212):

 
Expected behavior:
Enforcing the Default Flix Panel Duration preference should only affect the default duration for new panels.
 
Actual behavior:
Enforcing the Default Flix Panel Duration preference causes the Frame count of Sequences to behave incorrectly, which prevents new panels from being created or imported.
 
Workaround:
No known workaround at this time.
 
Reproduced by Support in:
