Custom video export presets installed by LrExportSettings.addVideoExportPresets() don't appear in the Export window when LR's language is set to any language except English.

To reproduce on LR 14.2 / Mac OS 15.3.2:
1. Download and uncompress this plugin:

2. Exit LR, reset LR's preferences and start LR.
3. In File > Plug-in Manager, add the plugin "video-preset-bug.lrdevplugin" from step 1.
4. Do File > Plug-in Extras > Video Preset Bug, which loads a custom video export preset called "My Preset".
5. Select a video and do File > Export > Export... In the Export window's Video panel, observe there is a File Handling menu with the item Custom Presets, and the custom video preset "My Preset" appears (correct):

6. Exit LR, reset LR's preferences and start LR.
7. In Preferences > General, set Language to Deutsch. Restart LR.
8. Repeat steps 3-5. But this time, observe that the Export window's Video panel doesn't contain the File Handling menu, and it isn't possible to select the custom video preset:
