[SDL3+Emscripten] 2 issues: nk_label_wrap bleeds and ui unresponsive?

Nobody has claimed this yet.

Hi, I have 2 problems: after using esc or q key for quitting the about popup, the whole ui is responsive and the first line manifest is bleeding?

code:
```
SDL_AppResult SDL_AppEvent(void *appstate, SDL_Event* event) {
[...]
/* Remember to always rescale the event coordinates,
* if your renderer uses custom scale. */
SDL_ConvertEventToRenderCoordinates(app->renderer, event);

nk_sdl_handle_event(app->ctx, event);
if ( event->key.key == SDLK_Q | event->key.key == SDLK_ESCAPE ) {
//SDL_Log("q pressed");
if ( show_app_about == nk_true ) {
show_app_about = nk_false;
return SDL_APP_CONTINUE;
}
if ( Show_Search_Menu == nk_true ) {
Show_Search_Menu = nk_false;
return SDL_APP_CONTINUE;
}
fprintf(stdout, "nk_false: %d\n", show_app_about);
return SDL_APP_CONTINUE;
SDL_Log("exited show_app_about state and returned");
}
if ( event->key.key == SDLK_A ) {
//SDL_Log("q pressed");
show_app_about = nk_true;
fprintf(stdout, "nk_true: %d\n", show_app_about);
return SDL_APP_CONTINUE;
}
if ( event->key.key == SDLK_SLASH ) {
SDL_Log("search key invoked");
//if ( Show_Search_Menu == nk_false ) {
Show_Search_Menu = nk_true;
//SDL_Log("search menu turned on");
//}
//if ( Show_Search_Menu == nk_true ) {
//Show_Search_Menu = nk_false;
//SDL_Log("search menu turned on");
//}
fprintf(stdout, "Show_Search_Menu: %d\n", Show_Search_Menu);
return SDL_APP_CONTINUE;
}

//SDL_Log("exiting event");
return SDL_APP_CONTINUE;
}

SDL_AppResult
SDL_AppIterate(void *appstate)
{
//SDL_Log("Aber i iterate");
struct nk_sdl_app* app = (struct nk_sdl_app*)appstate;
struct nk_context* ctx = app->ctx;

nk_input_end(ctx);

/* GUI */
if (nk_begin(ctx, "ic.wiki", nk_rect(0, 0, width, height), NK_WINDOW_BORDER|NK_WINDOW_MOVABLE|NK_WINDOW_SCALABLE|NK_WINDOW_MINIMIZABLE|NK_WINDOW_TITLE) ) {

nk_layout_row_static(ctx, (height/40), (width/20), 1);
if ( nk_button_label(ctx, "About") ) {
show_app_about = nk_true;
fprintf(stdout, "nk_true: %d\n", show_app_about);
//Open_Full_Dataset();
SDL_Log("button pressed");
}
}
[...]
if (show_app_about)
{
/* about popup */
if (nk_popup_begin(ctx, NK_POPUP_DYNAMIC, "About", NK_WINDOW_CLOSABLE|NK_WINDOW_SCALABLE, nk_rect( (width / 20) , (height / 20) , (width / 4), (height / 4) )))
{
nk_layout_row_dynamic(ctx, 10, 1);
//nk_layout_row_static(ctx, (height / 10), (width / 8.5), 50);
if (nk_tree_push(ctx, NK_TREE_NODE, "Manifest", NK_MAXIMIZED)) {
nk_label_wrap(ctx, "\176 ic.wiki is a site made by me to compare (hopefully) all of ic in the world in a flat fashion; tired to dumpster dive in to hundreds of nothingness pdf pages");
nk_label_wrap(ctx, "\176 The full dataset can be downloaded below:");
if ( nk_button_label(ctx, "https://ic.wiki/public/dataset-latest.csv.zstd") ) {

```

Start by reproducing the two reports in SDL_AppEvent and SDL_AppIterate with the supplied SDL3/Emscripten example: the unresponsive UI after closing the About popup and the bleeding first manifest line. Trace nk_sdl_handle_event, popup handling, and nk_label_wrap, then verify both behaviors are resolved in the same setup.
