Subject: Only issue currentWorkareaChanged() if the work area really changed.
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=f9dccb9afb9f47f724e4c24558b64baf3da4397b;p=lyx.git

Only issue currentWorkareaChanged() if the work area really changed.

(this function can be called repeatedly while the work area doesn't
change any further)

(cherry picked from commit fd78a25a7c0b307da32c7cd805ce9f101160610a)
