When CI runs and the site is being installed, during configuration import of webforms the message comes up that Bootstrap classes can not be found. This happens on line 79 of WebformElementManager.php, and may be intermittent.

To resolve I found discussion in the devel queue where users were having a similar problem, but this is specifically related to importing configuration for webform. (https://www.drupal.org/node/2853398)

I've attached their solution in the appropriate place for webform with a patch.

Here is the full error message during a cli installation:

Fatal error: Class 'Drupal\bootstrap\Bootstrap' not found in /mnt/tmp/local.prod/source/docroot/themes/contrib/bootstrap/bootstrap.theme on line 30

The latest release of the Webform module moved all Bootstrap related code into a dedicated and optional Webform Bootstrap module.

Are you still seeing this issue with the latest release of the Webform module?

I just experienced the error on CI jobs this morning, and resolved them with this patch. It's not necessarily because bootstrap code is being called, but the core drupal theme initialization is happening w/ getInfo before the classes are autoloaded for bootstrap.

This patch seems to be fixing a core issue that is affect the webform module. I can't replicate the issue so I am not comfortable applying this patch.

If this patch can be moved into the webform_bootstrap.module as an alter hook I would be okay with committing it.

I can confirm that this patch does indeed resolve the issue, which we encountered this week in a CI/CD deployment after installing webforms.
