Toolbar buttons for easypreset-created presets are disabled until you once enter toolbar editing settings panel

[pgavrilov]

What steps will reproduce the problem?

Bug appears after upgrade JOSM to version 17428

1. Install easypreset plugin
2. Open data layer and create tagged object that you will use as a sample for future preset. Select created object.
3. Create preset using easypreset plugin (menu Presets->Create preset).
4. Rename created preset using easypreset plugin (menu Presets->Manage custom presets) - it is minority bug of easypreset plugin, it creates new preset, but always names it as New Preset
5. Add toolbar button for created preset (menu Edit->Preferences->Toolbar; all easypreset-created presets placed into submenu actions->presets->custom presets)
6. Toolbar button is created and works fine. You can use it to change tagging for any appliable objects.
7. Restart JOSM and open data layer. All created at step 5 buttons are disabled and cannot be used.
8. Open toolbar editing settings panel again (menu Edit->Preferences->Toolbar) and immediately close it by pressing OK.
9. All created at step 5 buttons become enabled and now works fine.

What is the expected result?

Before JOSM upgrade to version 17428 was not any strange buttons disabling at JOSM restart.

Please provide any additional information below. Attach a screenshot if possible.

JOSM after restart and new data layer opening. Internal preset buttons are enabled, easypreset-created buttons are disabled

Could be a problem with user defined toolbar items in core. See #20665.

Or it is this old bug: #6725 ?
