Subject: do not change cursor position while replacing upload-placeholder
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=c47323e358b9841eb287c71e54ae549ea5f6d62d;p=friendica.git

do not change cursor position while replacing upload-placeholder

fixes #14695

Save caret position just before replacing the upload-placeholder.
replace upload-placeholder
Set caret position to the position in textarea as before replacing action.
Setting caret position considers the position before or after
placeholder and therefore the textlength of server-response to find the
right place.
