Subject: fix: crash when saving edited PDF files
|
|
|
|
This commit fixes a crash that persists any time a user attempts to
|
|
download an edited PDF. This was happening because the logic flow for
|
|
downloading of any edited PDF triggers a call to
|
|
chrome.fileSystem.chooseEntry, which we do not support and which
|
|
therefore causes unmapped page access crashes.
|
|
|
|
This patch can be removed should we choose to support chrome.fileSystem
|
|
or support it enough to fix the crash.
