[🐞] configTimeout not respected for value specified

[techfg]

Describe the bug

When configuring IM, the option configTimeout can be passed which indicates to IM how long to wait for images to load before failing initializing. This can be helpful when lots of alt images are used.

The option is documented to be an integer value in milliseconds with a default of 10,000. However, IM is failing initializing after 1/4 of the time specified for this value.
