Exception HbMustacheNameSynchronizer read access

[frederikbosch]

Recently I am seeing frequent exceptions like the one below.

com.intellij.openapi.diagnostic.RuntimeExceptionWithAttachments: Read access is allowed from inside read-action only (see Application.runReadAction()); If you access or modify model on EDT consider wrapping your code in WriteIntentReadAction ; see https://jb.gg/ij-platform-threading for details
