Folks:

Iǘe had this posted on the Gecko Github site for some time, but problem
persists in my Gecko Rolling MATE install as shown in the title, typing a
quotation makes it an ümlaut"and then after the second quote, hitting space bar
turns the second umlaut into a quote hash, but doesn´t add the space, as I have
demonstrated in subject line and again in the body of the text.

Problem has been going on for at least a month, doesn´t get resolved with
upgrades . . . .  I have a straight TW install, and a Leap 15.6 install on this
same machine w/o this issue.  Only the Gecko install seems to have the problem.
 Machine is ´12 Mac Pro . . . I have a newer ´20 linux laptop with a Gecko
Plasma install, no problems with it.
